Similarity and Congruence

This resource contains two instant maths ideas, ideal for use as starter activities, extension work or as probing questions to assess understanding. The activities provide students with the opportunity to consider what is meant by the term congruence, what properties two triangles must share in order for the triangles to be congruent and find shapes which can be cut up such that each of the smaller pieces is mathematically similar to the original shape.
