Methods Using Angles to Demonstrate That Two
... (Recall that we use the symbol ‘’ to mean ‘triangle’, and that triangles are often identified by list the symbols for their three vertices. Thus ABC denotes the triangle with vertices A, B, and C.) It is not necessary to use this “primed” notation, but your work in solving problems involving simil ...

Similar Triangles (F12)
... This just means that if two figures are similar then one can be “blown up” to match the other. The term similar may be applied to three-dimensional objects as well as plane objects. The two boxes in Figure 2 are similar. In this handout, we will be concerned with similar triangles. You could probabl ...

4.2 Some Ways to Prove Triangles Congruent
... cut and show 3 or 4 things are equal such as their face, age and height. If these are the same I think we can agree they are twins. The same is true for triangles. We don’t need to prove all 6 corresponding parts are congruent. We have 5 short cuts or methods. Today we will look at 3 methods. ...

Penrose tiling

A Penrose tiling is a non-periodic tiling generated by an aperiodic set of prototiles. Penrose tilings are named after mathematician and physicist Roger Penrose, who investigated these sets in the 1970s. The aperiodicity of the Penrose prototiles implies that a shifted copy of a Penrose tiling will never match the original. A Penrose tiling may be constructed so as to exhibit both reflection symmetry and fivefold rotational symmetry, as in the diagram at the right. A Penrose tiling has many remarkable properties, most notably:It is non-periodic, which means that it lacks any translational symmetry. It is self-similar, so the same patterns occur at larger and larger scales. Thus, the tiling can be obtained through ""inflation"" (or ""deflation"") and any finite patch from the tiling occurs infinitely many times.It is a quasicrystal: implemented as a physical structure a Penrose tiling will produce Bragg diffraction and its diffractogram reveals both the fivefold symmetry and the underlying long range order.Various methods to construct Penrose tilings have been discovered, including matching rules, substitutions or subdivision rules, cut and project schemes and coverings.
