triangles? Similar triangles are made by making bigger or smaller copies of a triangle – a transformation known as enlargement. Each of the triangles have equal corresponding angles, and corresponding sides that are in proportion to one another, for example each side of triangle ABC below is twice the length of each side on triangle ABC. There are four different ways to check if a pair of triangles are similar (see p.126), and if two triangles are known to be similar, their properties can be
