Question

triangle ABC is an isosceles right angle triangle in which angle A equal to 90 degree then find Angle B. ​

Answer 1

Step-by-step explanation:

Triangle ABC is an isosceles right angled triangle at angle A.

AB = AC

Therefore,angleC=angle B .......isosceles triangle theorem(1)

angle A+angle B+angle C = 180°

90+angle B+angle B = 180°.......From 1

2angle B = 90°

angle B = 45°

Answer 2

Answer:

angle b equal to 45 degree
