You've heard about similar triangles, but do you know what technically makes two triangles similar? Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Each angle in one triangle is congruent with (equal to) its corresponding angle in the other triangle i.e.:

In triangles, though, this is not necessary.

Similar triangles have the same 'shape' but are just scaled differently. Similar triangles, like all similar polygons, have congruent angles but proportional sides. They could be similar, but not necessarily. If two of their angles are equal, then the third angle must also be equal, because angles of a triangle always add to make 180 similar triangles are triangles with equal corresponding angles and proportionate sides.
