Angle Relationships

What is the Angle Relationship?

• Alternate Interior
• Alternate Exterior
• Corresponding
• Vertical

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.

Angle 1 and Angle 5 are examples of which type of angle pair?

• Alternate exterior angles

• Alternate interior angles

• Vertical angles

• Corresponding angles

Name the relationship of $\angle12\ \&\ \angle13$  

• alternate interior angleS
  

• corresponding angles

• alternate exterior angles

• vertical angles

• none

Angle 1 = 27^o Find the measure of angle 4

(Ask yourself: Are the angles inside or outside the parallel lines? AND Are they on the top or bottom of the transversal?)

• 27^o

• 153^o

• 63^o

• 90^o

1) Given the two parallel lines cut by a transversal.

What is the vertical angle to angle 4?

• Angle 2

• Angle 6

• Angle 8

• Angle 7

Vertical angles are always

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

Find the m∠1

(Ask yourself: Is angle 1 vertical or supplementary to the given angle?)

• 67

• 113

• 180

• 23
