Question

ABC is a right angle triangle in which angleA=90 and AB=AC ,Find angle B and angle C

Answer 1

Since one angle is 90 degree, sum of other two angles will be 90 degree.
Since, AB=AC

⇒ angles opposite to equal sides are equal.

⇒ angle B = angle C
So, both angles are 45 degrees each, which sum up to 90 degree.
