1.

In the triangles below AB = QR, BC = RP, CA = PQCompute ∠C of ∆ABC and all angle of ∆PQR.

Answer»

C = 80° (Use the property that the sum of three angles of a triangle is 180°)

AB = QR

∴ ∠C = ∠P

∠C = 80°

∴ ∠P = 80°

BC = RP

∴ ∠A = ∠Q

∠A = 40°

∴ ∠Q = 40°

CA = PQ

∴ ∠B = ∠R

∠B = 60°

∴ ∠R = 60°

(The angle opposite to equal sides are equal)
