Given the following two parallel lines that have been cut by a transversal. Which two angles would be Alternate Exterior?

Find the measure of angle 4

• 27^o

• 153^o

• 63^o

• 90^o

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

Find the m∠1

• 67

• 113

• 180

• 23

∠1 and ∠4

• Vertical Angles

• Linear Pair

• Corresponding Angles

• Transversal

Find the value of x.

• x = 10

• x = 20

• x = 720

• x = 5

Same Side Interior angles...

• Add to be 180

• Are congruent

• Add to be 90

• Are equal

If ∠5 ≌∠7, which of the following can be concluded?

• r is parallel to s by converse of Alternate Interior Angles Thm.

• u is parallel to v by Converse of Corresponding Angles Thm

• s is ⊥ u by Converse of Alternate Interior Angles Thm

• v ⊥ r by Converse of Alternate Exterior Angles Thm

What is the reason for Statement 4?

• Substitution

• Converse of Alternate Exterior Angles Theorem

• Converse of Corresponding Angles Postulate

• Converse of Same-side Interior Angles Theorem
