# Triangle ABC is a right triangle. What is the relationship between angles A and B?

We will use the concept of the right-angled triangle to find the relationship between angles A and B.

## Answer: Angles A and B are complementary angles.

Let us find the relationship between angles A and B.

**Explanation:**

The given triangle ABC is right-angled at C. This means ∠C = 90^{°}.

By angle sum property of triangle,

∠A + ∠B + ∠C = 180^{°}

∠A + ∠B + 90^{°} = 180^{°}

∠A + ∠B = 90^{°}

This implies ∠A and ∠B form a pair of complementary angles.
