About this worksheet

What students practice

Students add the measures of angle parts that sit side by side to find the whole angle.
Students subtract a known part from a whole angle to find an unknown angle in a diagram.
Students use right, straight, and full-turn angles (90°, 180°, 360°) to find missing angles.

How to use

Use after students can measure angles with a protractor. Remind them that the parts of each fan sit side by side with no gaps or overlaps, so the parts add up to the whole angle.
