Tick the correct answer and justify:

Inand the angle B is:


A. 120° B. 60°


C. 90° D. 45°

Given that, AB = 6 cm,

AC = 12 cm,


And BC = 6 cm


It can be observed that


AB2 = 108


AC2 = 144


And, BC2 = 36


AB2 +BC2 = AC2


ΔABC, is satisfying Pythagoras theorem.


Therefore, the triangle is a right triangle, right-angled at B


∠B = 90°


Hence, the correct answer is (C)
