Question

In a Right Angled Triangle ABC where angle A= 90° and AB=AC. What is measure of angle B ?​

Answer 1

Answer:

45°

Step-by-step explanation:

Since two sides are equal angles opposite to sides are also equal i.e. angle B=C

using sum of all angles of triangle is 180°

A+B+C=180°

90°+B+B=180°

2B=90°

B=45°

Answer 2

Step-by-step explanation:

If angle A measures 90°

Then AB=AC...

Then it is a right angled isosceles triangle...

we know that :-angle A + angle B+ angle C=180°

angle B +angle C= 90°

angle B=angle C-------[as AB=AC]

SO Angle B=45°,Angle C=45°

HERE IS UR SOLUTION...
