Question

In triangle pqr angle P is equal to 60 degree if pq is equal to p r find angle q and angle r what kind of triangle is ​

Answer 1

Step-by-step explanation:

Since PQ = PR

its angles opposite to the equal sides will be equal

angle Q = angle R

let angle Q be x

angle R = x

In Triangle PQR

angle P + angle Q + angle R = 180° (alternate interior angles)

60° + x + x = 180°

2x = 180° - 60° = 120°

x = 120°/2 = 60°

Since all angles are equal, i.e, 60°

Therefore, Triangle PQR is equilateral triangle
