Inspired by ancient Egyptian iconography and abstract art, the symbolism behind the Shen Bracelet can be found represented in hieroglyphs as a stylized loop of a rope with a circle and a line tangent to it. In ancient Egyptian, the word shen itself means encircle, while the shen ring betokens eternal protection.

This text book introduces a comprehensive study on two dimensional conic sections, pair of straight lines, circles, ellipses, parabolas, and hyperbolas (standard and general forms). It focuses mainly on the study of tangent lines, normal lines, tangential chords, pole and polar, reflection properties, relations between such studied objects, translations, and rotation of axes. The text book ends with displaying some of their important applications.
Why can't we learn mathematics with our hands and our brains?! This block kit puts trigonometry directly in your hands. Sine, Cosine, Tangent, and the other trig functions take physical form and become real. Students can explore, with their own hands, the definition of the radian unit of angular measurement and even come up with their own approximation of Pi. The material is high quality precision-cut Birch verner pure bond plywood. No assembly required. Kit comes with a step-by-step educational guide. Includes the unit circle, three 30-60-90 triangles, two 45-45-90 triangles, two circular sectors, and Kepler's triangle. The trigonometric functions are some of the most important and useful tools within STEM fields. They show up from engineering to quantum mechanics and everything in between. This block kit gives physical intuition to this critical STEM tool. Kit includes the unit circle and the ever important 30-60-90 and 45-45-90 triangles. The included pedagogy walks students through the definition of all six trigonometric functions, and uses the properties of similar triangles and the Pythagorean theorem to help students establish the critical relationships between them. Also included are 1 radian and 2 radian circular sectors. These allow students to explore the definition of the radian unit of angular measurement with their hands. Then can then use these tools to come up with their very own approximation of Pi. Finally, Kepler's triangle (which is related to the Fibonacci sequence) provides a vehicle to test one's understanding since the trig functions of its angles can all be expressed in terms of the golden ratio.

We split up our circles unit into 2 parts (Part 1: Circle Basics, Circumference & Area, Area of Shaded Regions, & Tangent Lines; Part 2: Arcs, Central Angles, Chords, Sector Area, Arc Length, and Segment Area). I know a majority of schools teach circles as one big unit but I don't think that most of my special education students could remember all of those theorems and rules and be successful. For those that teach circles as one big unit and your students are successful, can you show me a sample of your unit outline? :) Day 1: We used the foldable below to learn about the basic parts of a circle. I LOVE this foldable and have used the same one for the past 3 years. Students choose one color to represent each vocabulary word and color-code accordingly. I found that this helps students out A LOT! I really emphasized the difference between a secant and a chord. Also, when listing chords, some students forget to write down the diameter down so I reminded students that the diameter is the longest chord in a circle. Identifying all the radii in the circle helped students realize that even though a line is not drawn, it is still a radius! After the notes on our foldable, I told students to close their foldable and attempt the blue sheet (vocabulary review) by themselves. I told them to read through the definition and draw a picture. About 85% matched the vocabulary word with the definition correctly with the most common mistakes of switching tangent and secant. I had too much time left in class so I decided to start circumference and area notes. I labeled the purple sheet with the students before introducing the flip-book. On the purple sheet I had students write down d=2•r and r = 1/2•d (even though it is not shown in the pictures). We only went through the vocabulary, circumference, and area sections of their flip-book. These examples were easy and a quick review of what they already know about circumference and area. Overall, the vocabulary, circumference, and area section took about 15 minutes to complete (and most students finished the examples before I was even done!) After the notes, I handed them the following homework to complete over circle basics. I did have to to remind students again that the diameter is a chord in problem #4. Day 2: Students walked in and opened up to their circumference and area foldable. Before we got started, I cold called on several students and asked them questions over circumference and area. Some sample questions that I asked students were, "If the diameter of a circle is 10m, then what is the length of the radius?" "If the circumference of a circle is 56⫪, then what is the radius of the circle?" "If the area of a circle is 49⫪m², then what is the circumference of the circle?" After I had several students answer my questions, we started on the more circumference and more area sections in our flipbook. Many students got stuck/had questions on the square inscribed in the circle problem (on finding the diameter). After the notes, I handed students the following circumference and area homework. Students had the most questions on the diameter on question #8 since we have not practiced 45-45-90 triangles in a minute :) Day 3: Students walked in and cut out their area of shaded regions foldable and taped it down next to their review of area formula chart. I am so glad that I made this review of area formula chart to place next to their area of shaded regions foldable because many students referenced this when we got to the homework. In many of my classes, I have to tell students how to find the area in very clear and concise ways or I will lose/confuse many of them. For example, I told students that to find the area of the shaded region in example 4 we will use the following formula: "area of the big circle - area of medium circle - area of the small circle." After the notes, I had students complete the following area of shaded regions homework. Again, most students had questions on how to find the diameter of the circle in question 4 (just like circumference & area) so in my lower level classes, we went over question #4 together. Day 4: Today we did the following tangent lines foldable together as a class. We completed the foldable first and then summarized our findings on the blue graphic organizer. Students really understood the concept of tangent lines after this lesson. Question #3 was definitely my favorite question on this foldable :) After the foldable, we completed the following worksheet over tangent lines and students did GREAT on this formative assessment. Most of my special education students could complete #5 correctly, even though there was not a question like this on our notes (big deal in my class).

The NWi NSLP500B Transit Level Package is for builders and surveyors that require horizontal angle measurements, plumbing vertical columns, measuring property lines, excavating trenches and running pipelines. This optical instrument has a working range of up to 200 feet and provides 20x magnification. It also features clamps and tangents that bring the instrument quickly on target and includes a heavy-duty aluminum tripod and 9' grade rod (feet and inches) for fast setup and stable measurements. The NSLP500B is capable of measuring vertical angles ±45 degrees and horizontal angles to within 1-degree accuracy. It can also be used as a level by locking the telescope into place. Its level vial has an accuracy of 1/4-inch at 100 feet, making it ideal for elevation measurements and grading applications. For easy level rod readings, this transit level’s telescope has exceptionally clear optics and stadia lines allowing you to determine the distance of the transit from the level rod.

Here we will learn about Secant and Tangent. Let a circle with centre O and a straight line AB be drawn on the same plane. Then only one of the following cases is possible: (i) The straight line AB does not touch or cut the circle at any point. (ii) The straight line AB cuts

During this self-paced worksheet activity, students use algebra and the Pythagorean Theorem (and/or Pythagorean Triples) to practice the following circle tangent properties: · If a circle has 2 intersecting tangents, then the tangent lengths from the points of tangency to the intersection are equal. · A circle’s tangent is perpendicular to the radius at the point of tangency.
