# Angle A is a right angle in △ABC. Which side is opposite to angle A?

Triangles are 3-sided polygons that are of many types. The triangle which has one of its angles as 90 degrees is called a right-angled triangle.

## Answer: In the above triangle △ABC, the side opposite to angle A is BC.

Let's understand the solution.

**Explanation:**

The opposite side to a particular angle in a triangle is that side that doesn't contain that particular angle.

From the above figure, we see that both sides AB and AC contain angle A.

Only, side BC doesn't contain angle A.
