6th through 8th Grades

Complementary Angles

Pairs of complimentary angles are shown. The measurement of one is given. Students must calculate the measurement of the other.
6th through 8th Grades
This worksheet serves as a basic introduction to complementary angles. At the top, the concept is described. At the bottom, students are instructed to find the complement to each angle shown.
6th through 8th Grades
Cut out the angle tiles at the bottom of the page. Glue each angle next to it next to its complement.
6th through 8th Grades

Supplementary Angles

On each problem, students are shown two angles. The measurement of one angle is known. The other is the supplement, which must be calculated.
6th through 8th Grades
This is a very basic introduction to supplementary angles. At the top of the page is an explanation box. Then students are shown nine angles. They need to find the supplement for each.
6th through 8th Grades
Cut out the angle picture squares at the bottom of the worksheet. Then glue each one next to its supplement.
6th through 8th Grades

Adding Adjacent
Angles Together

This page has illustrations of 2 adjacent angles. Students must recognize the combined angle as additive. There's also an angle word problem that requires students to divide.
4th and 5th Grades

Complementary, Supplementary, & Vertical Angles

Identify complementary, supplementary, and vertical angles. Calculate the number of degrees in each unknown angle.
6th through 8th Grades
This page has information about complementary, supplementary, and vertical angles, with examples. At the bottom, students identify the angle type and calculate the unknown measurements.
