In two triangles DEF and PQR, if DE = QR, EF = PR and FD = PQ, then

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

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

In ∆PQR, if ∠R > ∠Q, then

In the given figure, if the exterior angle is 135^o then ∠P is:

It is given that Δ ABC ≅ Δ FDE and AB = 5 cm, ∠B = 40° and ∠A = 80°. Then which of the following is true?

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

In triangle ABC, AB = AC and angle A : angle B = 8 : 5 , find angle A .

In triangles ABC and PQR, AB = AC, ∠C = ∠P and ∠B = ∠Q. The two triangles are:
