Angle relationships with Parallel Lines and a Transversal

Front

What are Alternate Exterior Angles?

Back

Angles that are on opposite sides of a transversal and outside the two lines.

Front

What are Corresponding Angles?

Back

Angles that are in the same position on two parallel lines in relation to a transversal.

Front

What are Vertical Angles?

Back

Angles that are opposite each other when two lines intersect; they are always equal.

Front

What are Complementary Angles?

Back

Two angles that add up to 90 degrees.

Front

What are Supplementary Angles?

Back

Two angles that add up to 180 degrees.

Front

If angle A and angle B are supplementary and angle A measures 70 degrees, what is the measure of angle B?

Back

110 degrees.

Front

If angle C and angle D are complementary and angle C measures 30 degrees, what is the measure of angle D?

Back

60 degrees.

Front

What is the equation to find the value of X if 8X - 17 + 5X + 19 = 180?

Back

8X - 17 + 5X + 19 = 180.

Front

What is the equation to solve for X if 12X - 19 + 4X + 1 = 180?

Back

12X - 19 + 4X + 1 = 180.

Front

What is the relationship between Alternate Interior Angles?

Back

They are equal when two parallel lines are cut by a transversal.
