Question

In a right angle triangle PQR, 2 of its sides PQ and QR are equal. Find all angles of a triangle PQR.​

Answer 1

Answer:

45°,45°,90°

Step-by-step explanation:

As the two angles of The equal sides of an isosceles triangle are equal,

QPR = PRQ = x

sum of angles in a triangle = 180°

x + x + 90° = 180°

2x = 90°

x = 45°

Answer 2

Answer:

In triangle PQR

PQ = QR

angle PQR = 90

Let angle QPR be x

angle QPR = angle QRP ( angles opposite to equal sides are equal)

Now,

x+x+90=180( angle sum property )

2x= 90

x= 45
