**Learn the difference between a complementary and supplementary angle in Math.**

**Complementary angles** are two angles that add to 90 degrees.

**Supplementary angles** are two angles that add to 180 degrees.

Here are some examples of complementary angles:

- The angle between the hour hand and minute hand of a clock at 3:00 is 90 degrees.
- The angle between the two legs of a right triangle is 90 degrees.
- The angle between the two lines of a highway that intersect at a right angle is 90 degrees.

Here are some examples of supplementary angles:

- The angle between the two hands of a clock at 6:00 is 180 degrees.
- The angle between the two sides of a parallelogram that are opposite each other is 180 degrees.
- The angle between the two lines of a highway that run parallel to each other is 180 degrees.

**Complementary and supplementary angles** are important concepts in geometry and trigonometry. They are used in many different applications, such as navigation, surveying, and construction.
