What is the relationship between angle 4 and angle 5 called?

• Vertical Angles

• Alternate Exterior Angles

• Alternate Interior Angles

• Same Side Interior Angles

Are the two triangles considered similar based on the given information.

• Yes, because of Angle-Angle Theorem

• Yes, because of Side-Angle-Side Theorem

• No, because the side lengths are not the same length

• Not enough information
