Find Missing Angles of Parallel Lines Cut by a Transversal

If angle 1 is 135 degrees, how many degrees is angle 3?

• 45 degrees
• 65 degrees
• 135 degrees
• 225 degrees

If angle 8 is 70 degrees, how many degrees is angle 2?

• 20 degrees
• 70 degrees
• 110 degrees
• 130 degrees

If angle 8 is 63 degrees, how many degrees is angle 2?

• 63 degrees because angle 8 & 2 are alternate exterior angles.
• 117 degrees because angle 8 & 2 are supplementary.
• 63 degrees because angle 8 & 2 are vertical angles.
• 117 degrees because angle 8 & 2 are same side 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
