Understanding Complementary and Supplementary Angles

In geometry, angles play a significant role in defining the shape and size of figures. Two important types of angles are complementary angles and supplementary angles, which have specific relationships and properties.

Complementary Angles, Complementary and supplementary angles worksheet answers

• Complementary angles are two angles whose sum is 90 degrees.
• In other words, they are angles that add up to a right angle.
• For example, if one angle measures 30 degrees, its complementary angle will measure 60 degrees.

Supplementary Angles

• Supplementary angles are two angles whose sum is 180 degrees.
• In other words, they are angles that add up to a straight line.
• For example, if one angle measures 120 degrees, its supplementary angle will measure 60 degrees.

Identifying Complementary and Supplementary Angles: Complementary And Supplementary Angles Worksheet Answers
