Question

∆ABC ~∆QPR, if angle A: angleB: angleC= 1:2:3 then the measure of angleR is​

Answer 1

Answer:Given :   in triangle ABC and PQR, angle A= angle Q and angle B= angle R

To find : Which side of triangle PQR should be equal to side AB of triangle ABC so that the two triangles are congruent

Solution:

∠A   = ∠Q

∠B  = ∠R

=> ∠C  = ∠P    (

Δ ABC  ≈ Δ QRP

=>   Δ ABC  ≅ Δ QRP

if AB  = QR

QR should be equal to AB
