What is the symbol of congruence is?

The symbol ≡ means “is congruent to”. Two triangles are similar if they have the same shape. Two similar triangles are equiangular, i.e., angles which correspond are equal.

How many types of similarity are there?

Answer: There are four similarity tests for triangles. If two angles of one triangle are respectively equal to two angles of another triangle, then the two triangles are similar. It is sufficient to prove that only two pairs of angles are respectively equal to each other.
