Complementary angles?

Complementary angles are two angles that add up to 90 degrees. In other words, when the two angles are placed next to each other, they form a right angle. For example, if one angle measures 30 degrees, the complementary angle would measure 60 degrees in order to add up to 90 degrees.

Complementary angles are two angles whose sum is 90 degrees. They are often found in pairs, such as in a right triangle, where the two acute angles are complementary.

Properties of complementary angles:

- Their sum is 90 degrees.
- They are always adjacent to each other.
- They can be formed by dividing a right angle into two equal parts.

Examples of complementary angles:

- A 30-degree angle and a 60-degree angle
- A 45-degree angle and a 45-degree angle
- A 60-degree angle and a 30-degree angle

Applications of complementary angles:

- They are used in geometry to find missing angle measures and to prove theorems.
- They are used in trigonometry to calculate the sine, cosine, and tangent of angles.
- They are used in physics to calculate the angles of incidence and reflection of light and other waves.
