# State whether the following right-angled triangles are similar or not:

Answer :

Two polygons of a same number of sides are similar, if

a) all the corresponding angles are equal.

b) all the corresponding sides are in the same ratio (or proportion)

In case of right-angled triangle PQR and ABC

and

The corresponding sides of a right-angled triangle ABC and PQR are proportional, and their corresponding angles are not equal. Hence, triangles ABC and PQR are not similar.
