Angles Complementary Supplementary Vertical

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°

Vertical angles are always

• acute

• total 180 degrees

• congruent (equal measures)

• adjacent angles

What kind of angles are shown?

• complementary

• supplementary

• adjacent

• corresponding

∠1 and ∠3 can best be described as - 

• complementary angles

• supplementary angles

• vertical angles

• adjacent angles

Find the missing angle.  Find x.

• 20^o

• 70^o

• 160^o

• 180^o

What is the equation that could be used to solve for the missing angle measure?

• x + 64 = 90

• x = 64

• x + 64 = 180

• 90 - x = 64

Solve for b
