What is a Complementary Angle?

A set of complementary angles is defined as any two angles that, when added together, will equal 90 degrees. Complementary angles are often used in geometry and trigonometry to solve various problems involving right angles.

Example Calculation 1

Let's assume the following value:

Using the formula:

\[A = 90^\circ - 30^\circ = 60^\circ\]

The Complementary Angle is 60°.

Example Calculation 2

Let's assume the following value:

Using the formula:

\[A = 90^\circ - 45^\circ = 45^\circ\]

The Complementary Angle is 45°.
