Question

AM=BM=CM
Angle ACB=?​

Answer 1

• According to given things on your book

• m is the midpoint so MB = AM = CM and is equal to height.

• if we see then there two isosceles triangle in one triangle.

• angle CM is 90° because height is perpendicular.

• then two remaining sides will be 45 ° ..as 180 - 90 = 90° half of 90° is 45°

• so angle ACB = 45° + 45° = 90°
