Question

In ∆PQR, PQ = QR and ∠R = 50°, then find the measure of ∠Q.​

Answer 1

Answer:

given that in PQR .

PQ=QR

so it becomes an isosceles triangle.

so,angles corresponding to equal sides are always equal.

<R=<Q

so, <Q=50⁰

Answer 2

Step-by-step explanation:

Using concepts:-

• The sum of all the three angles in a triangle is 180°.
• Angles opposite to equal sides are equal.
• If two sides are equal then the triangle is an Isosceles triangle.
