Question

ABC is a right angled triangle in which angle A= 90 degrees and AB=AC. show that angle B =angle C.​

Answer 1

Answer:

If AB = AC

angle B=angle C

it is one of the theorem

Answer 2

Step-by-step explanation:

Given

Angle A =90

AB=AC

Draw Ad perpendicular to BC

given AD Bisect B

From triangle ABC, ACD

ANGLE BDA=ANGLE CDA=90 (GIVEN)

AB = AC (GIVEN)

AD=AD (COMMON SIDE)

THEREFORE TRAINGLE ABD CINGRUENT TO TRAINGLE ACD

THEREFORE ANGLE B=C
