6th Grade Math

There are six sets of angle worksheets:

- Angles on a Straight Line
- Angles at a Point
- Vertical Angles
- Complementary Angles
- Supplementary Angles
- Complementary & Supplementary Angles

Examples, solutions, videos, and worksheets to help grade 6 learn how to find unknown angles using the complementary and supplementary angle properties. There are also word problems that involve complementary and supplementary angles.

There are three sets of complementary & supplementary angle worksheets.

- Find unknown angles in a diagram.
- Complementary angle word problems.
- Supplementary angle word problems.

Complementary angles and supplementary angles are pairs of angles with specific relationships. Complementary angles add up to 90 degrees, while supplementary angles add up to 180 degrees. You can find these angles by solving equations based on these relationships.

- Complementary Angles:

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

Let one of the angles be x degrees. The other angle, which is complementary to it, will be (90 - x) degrees. For example, if one angle is 45 degrees, the complementary angle is 90 - 45 = 45 degrees. - Supplementary Angles:

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

Let one of the angles be x degrees. The other angle, which is supplementary to it, will be (180 - x) degrees.

For example, if one angle is 120 degrees, the supplementary angle is 180 - 120 = 60 degrees.

Have a look at this video if you need to review how to find unknown angles using the complementary and supplementary angle properties.
