Angle Relationships & Unknown Values #3

Brush up on complementary, supplementary, vertical, and adjacent angles with this helpful worksheet! Students will study each diagram and write an equation to solve for the missing value. Once they have identified the value of the variable, learners will cross it off from the table, allowing them to check and correct their work if their answer isn’t in the list.

This worksheet provides seventh graders with practice applying the relationships of complementary, supplementary, vertical, and adjacent angles. By solving for each missing value, students will also gain experience writing and solving multi-step, one-variable equations. These skills will support learners as they dive deeper into geometry.

Be sure to complete the first two worksheets in this series, Angle Relationships & Unknown Values #1 and Angle Relationships & Unknown Values #2. For more practice, try Solving Problems Using Angle Relationships #1.
