• 

What would the last given to finish the proof

• Converse of Alternate Exterior Theorem

• Converse of Alternate Interior Theorem

• Converse of Corresponding Angle Postulate

What is This Property:

The two angles are on one side of the transversal, yet are inside the two parrallel lines:

• Cons. Int.
  

• Cons. Ext.

• Both

• Neither

• I don't know

In the proof shown, what would be reason 2?

• Corresponding Angles Postulate

• Linear Pair Postulate

• Alternate Exterior Angles Theorem

• Vertical Angles Theorem

• Angle Addition Postulate

Which of the following would justify the statement \angle1\cong\angle3

• given

• converse of the alternate exterior angles theorem

• corresponding angles postulate

• transitive property of congruence

Given the figure, which of the following are valid?

• Angle 2 is congruent to angle 4 because they are a linear pair

• Angle 5 is supplementary to angle 2 because they are corresponding angles

• Angle 6 is supplementary to angle 3 because they are same side exterior angles

• Angle 4 is congruent to angle 6 because they are corresponding angles

• Angle 2 is congruent to angle 1 because they are alternate interior angles

The bolded angle measures _________________ degrees (do not include the units in you answer)

What is the measure of the angle with the question mark? (enter the number only, not the units.) The measure of the angle is ________________degrees.

Choose the theorem that would best be used to prove the following statement, given that lines r and s are parallel and lines t and u are parallel. : If the m∠3 = 120˚, then m∠5 = 120˚

• Corresponding Angles Postulate

• Same Side Interior Angles Theorem

• Alternate Interior Angles Theorem

• Alternate Exterior Angles Theorm

• Same Side Exterior Angles Theorem

7. Given that a || b are parallel: If the m∠1 =4x + 22 and m∠8 = 7x - 14, what is the value of m∠3? (enter the number only, not the degrees)
