Question

2. ABC is a right-angled triangle in which A = 90° and AB = AC. Find B and c​

Answer 1

Answer:

as ab=ac abc is an isosceles right triangle

=>b=c=x

therefore

a+b+c=180 (angle sum property)

a+x+x=180

2x=180-90

x=45

=>b=c=45

Answer 2

Since, AB=AC

Therefore, B°= C° ___(1)

So, angle A+ angle B+ angle C= 180°

90° +2angleB=180

angleB= 90°

angleB= angle C= 45 ___(From 1)
