About this worksheet

What students practice

  • Students add the measures of angle parts that do not overlap to find the measure of the whole angle.
  • Students write and solve an equation with a symbol to find an unknown angle in a diagram.
  • Students use right angles, straight angles, and full turns to find missing angle measures.

How to use

Use after students can measure angles with a protractor. Before the missing-angle problems, review that a right angle is 90°, a straight angle is 180°, and a full turn is 360°.

Curriculum

Common Core standard covered
