About this worksheet

When two lines cross, the angles opposite each other are vertical angles and are equal. Angles next to each other on a straight line form a linear pair and add up to 180°.

Teaching tip

Have students write the relationship ("vertical, so equal") next to each answer. Naming it is the skill the test asks for.
