If two similar triangles are of equal areas, then the two triangles are ….

If the area of two similar triangles are equal then the triangles are congruent.

Theorem 6.3 : If in two triangles, corresponding angles are equal, then their corresponding sides are in the same ratio (or proportion) and hence the two triangles are similar.

Write the truth value (T/F) of each of the following statements: Two polygons are similar if their corresponding angles are proportional. Two triangles are similar if their corresponding sides are proportional.(iii) Two triangles are similar if their corresponding angles are proportional.

Introduction || Corresponding sides OF similar triangles are proportional but angle are same || Condition for two figure are similar

If two angles of one triangle are respectively equal to two angles of another triangle; then two triangles are similar.
