Practice With Angle Pairs

What are vertical angles?

• Angles that are adjacent to each other

• Angles that add up to 180°

• Angles that are opposite of each other when lines intersect

• Angles that add up to 90°

Tell whether the angles are complementary or supplementary. Then find the value of x.

• Complementary; x=25
• Complementary; x=5
• Supplementary; x=25
• Supplementary; x=5

Which are pairs of vertical angles?
