Question

in triangle pqr if pq=qr=pr then prove that angle p is equall to angle Q is equall to angle R is equall to 60 degree​

Answer 1

Step-by-step explanation:

As all the sides are equal,

PQ=QR=PR

So,

Angle P= Angle Q= Angle R

So all the angles are equal

So let the angles be x

x+x+x= 180°

3x= 180°

x=60°

Hope it will help you.......

Answer 2

Step-by-step explanation:

as all the sides are equal, the triangle is an equilateral triangle.

each angle of an equilateral triangle is equal.

let each angle be x

then the sum of all angles would be 3x

also, 3x=180°

so, x=180/3=60

hence, each angle is of 60°
