Missing angle measures

What is the relationship between angle 1 and 2?

• Supplementary
• Complementary
• Vertical
• Obtuse

What are complementary angles?

• Angles that add up to 180°
• Angles that add up to 90°
• Angles that are equal to each other
• Angles that are opposite of each other when lines intersect.

What type of angle measures 90 degrees?

• acute
• obtuse
• right
• straight

What is the complement of 62 degrees?

• 18°
• 28°
• 38°
• 118°

• x = 118
• x = 108
• x = 28
• x = 58

∠1 and ∠3 can best be described as -

• complementary angles
• supplementary angles
• vertical angles
• adjacent angles

If m∠1 = 30°, then m∠3 = 

• 30°
• 60°
• 150°
• undetermined

Find the m∠3

• 56
• 124
• 180
• 66

What angle is vertical to angle 2?

• ∠4

• ∠1

• ∠2

• ∠5

Solve for x

• 6
• 140
• 20
• 90
