Which of the following is not a criterion for congruence of triangles?

If AB = QR, BC = PR and CA = PQ, then

In ΔABC, BC = AB and ∠B = 80°. Then ∠A is equal to

Two sides of a triangle are of lengths 5 cm and 1.5 cm. The length of the third side of the triangle cannot be

In triangles ABC and DEF, AB = FD and ∠A = ∠D. The two triangles will be congruent by SAS axiom if

If all the three angles of a triangle are equal, then each one of them is equal to

If two acute angles of a right triangle are equal, then each acute is equal to

An exterior angle of a triangle is equal to 100° and two interior opposite angles are equal. Each of these angles is equal to

If the sides of a triangle are produced in order, then the sum of the three exterior angles so formed is

In Δ ABC, if ∠A = 100° AD bisects ∠A and AD⊥BC. Then, ∠B =
