Recognizing Angle Relationships

Given the following two parallel lines cut by a transversal. Which pair of angles represents alternate exterior angles?

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

Find the value of x.

• 31

• 61

• 91

• 1

What is the measure of ∠ABC?

• 25°

• 75°

• 108°

• 150°

Which is the correct way to state that these lines are perpendicular?

• 
• 

Which pair of angles is an example of consecutive interior angles?

What is the angle relationship between <3 and <5?

• Corresponding Angles

• Alternate Interior Angles

• Alternate Exterior Angles

• Consecutive Interior Angles

What is the relationship of the angles?

• Corresponding angles

• Same Side Interior

• Alternate Interior

• Alternate Exterior

Find the missing angle.  Find x.

• 20^o

• 70^o

• 160^o

• 180^o

Vertical angles are always

• acute

• total 180 degrees

• congruent (equal measures)

• adjacent angles
