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.

Thus, angles A and B are a pair of complementary angles.
