• Supplementary Angles

• Vertical Angles

Supplementary angles always add up to

Complementary angles always add up to

Which angles are vertical angles?

• $\angle8\ \&\ \angle7$

• $\angle8\ \&\ \angle6$

• $\angle8\ \&\ \angle5$

This is what kind of angle?

• obtuse
• right
• straight
• acute

Vertical angles are always

• acute
• total 180 degrees
• congruent (equal measures)
• adjacent angles

What is the value of x?

• 37
• 72
• 108
• 18

• x = 118

• x = 108

• x = 28

• x = 58

• x = 56

• x = 66

• x = 156

• x = 166

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
