a tessellation of a single symmetric pentagon, can have (several) equal sides, two (opposite) right angles these come in various forms (have degrees of freedom) found in Cairo as paving tiles (not that old) what relationship is there between the angles if two are right angles and two of the other (obtuse) angles are equal? what if the 3 obtuse angles are equal? David Bailey (from Grimsby, England, with a keen interest in recreational mathematics) has undertaken a very thorough analysis of the variety and dates of 'in situ' tiles so far the oldest dated version he has been able to establish is 1956 due to the two 90 degree angles in the pentagon the tessellation(s) have a 'skeleton' (as David Wells calls them) of squares so the variety of this type of tessellation is created by the different angles in the rhombus: the pentagon tessellation can be viewed with other square 'skeletons' or another way are these squares? or with isosceles (at least) triangles what relationship is there for the apex and two equal base angles? or with trapeziums what is the relationship here? a version of the tiling can be created from the 4, 3, 3, 4, 3 semi-regular tessellation, as a dual (corners of the original tessellation become centres of the related one - and vice versus) what are the angles in the tiles? are the tiles congruent? a tessellation of Cairo-like tiles can be drawn on isometric paper but... there are two different types of (non-congruent) pentagon here establish that their angles are the same David Bailey quotes Robert H Macmillan's claim that collinearity is a feature of some of the 'Cairo' tessellations and explores this four of the sides are the same length what are the angles in each pentagon tile for this arrangement? use trigonometry to establish the angles in each pentagon for this arrangement what collinearity is there? it is possible to have all the sides the same length what are the angles for this equilateral pentagon tile? if the triangle formed by joining the apex of the pentagon to the two bottom corners is equilateral there is a collinearity the triangle shown is equilateral find angle 'a' and establish the (seeming) collinearity property
