By which congruence rule are triangle PRQ and triangle TRS congruent?
If two right-angled triangles have their hypotenuses and one side equal, then the two triangles are congruent by SAS congruence rule.
In Fig 7.32, measure of some parts of triangles are given. By applying RHS congruence rule, state which pairs of triangles are congruent. In case of congruent triangles, write the result in symbolic form.
