Identifying Angle Relationships

What type of angle pair is shown?

• complementary

• supplementary

• vertical

What angle relationship is shown?

• Complementary 

• Supplementary

• Vertical

• None of the above

What are supplementary 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

Vertical angles are always

• acute

• total 180 degrees

• congruent (equal measures)

• adjacent angles

Find the measure of angle b.

Hint: Identify the angle relationship.

• 30

• 120

• 60

The angle relationship shown is - (a)  

• complementary angles

• supplementary angles

• vertical angles

• angle bisector

Find the measure of angle b.

Hint: Identify the angle relationship.

• 95

• 85

• 5

• 2x - 6 = 7x + 4

• 9x - 2 = 90

• 9x + 2 = 180

• 9x + 10 = 90
