Review the basics of complementary and supplementary angles, and try some practice problems.

Learn about complementary and supplementary angles, as well as the definitions of adjacent and straight angles.

Figure out what all of the angles are, and then use the fundamental definitions, your sohcahtoa definitions, to see if you can figure out what sine of 32 degrees is.

Use your knowledge about complementary and supplementary angles to find missing angles.

Practice telling whether two angles are supplementary, complementary, or vertical.

Learn about the relationship between the sine & cosine of complementary angles, which are angles who together sum up to 90°.

In every right triangle, the two non-right angles are complementary. This is because the angles of a triangle add to 180º, so if the three angles are x, y, and 90º, then x+y+90º=180º Subtract 90º from …

Angle relationships like complementary, supplementary, vertical, and adjacent allows you to compare angles, find missing angles, see if an angle is greater/less than another one, etc.

In this topic, we will learn what an angle is and how to label, measure and construct them. We will also explore special types of angles.
