Question

triangle triangle ABC and PQR are both isosceles with AB=AC and PQ=PR respectively.If also,AB=PQ andBC=QR, are the two triangle congruent? which condition do you use? If angle B=50°, what is the measure of angle R ?

​

Answer 1

∠R = 50° using SSS congruency

Step-by-step explanation:

Given that

In ΔABC and ΔPQR,

AB = AC

PQ = PR

∠B = ∠C = 50°  

∠Q = ∠R

AB = PQ

BC = QR

AC = AB = PQ = PR

∵ AC = PR

Using the SSS congruence rule,

ΔABC ≅ ΔPQR

∵ ∠B = ∠C = ∠R = 50°
