Parallel Lines Cut By Transversals!

Front

What is a transversal?

Back

A transversal is a line that intersects two or more lines at different points.

Front

What do supplementary angles add up to?

Back

Supplementary angles add up to 180 degrees.

Front

What are corresponding angles?

Back

Corresponding angles are angles that are in the same position on two parallel lines cut by a transversal.

Front

What are alternate interior angles?

Back

Alternate interior angles are angles that are on opposite sides of the transversal and inside the two lines.

Front

What are same side interior angles?

Back

Same side interior angles are angles that are on the same side of the transversal and inside the two lines.

Front

If angle 3 measures 72 degrees, what is the measure of angle 5?

Back

Angle 5 measures 72 degrees because it is an alternate interior angle to angle 3.

Front

If angle L is 51 degrees, what is the measure of its corresponding angle?

Back

The corresponding angle to angle L is also 51 degrees.

Front

If two angles are supplementary and one measures 100 degrees, what is the measure of the other angle?

Back

The other angle measures 80 degrees.

Front

What is the relationship between parallel lines and transversals?

Back

When a transversal cuts parallel lines, it creates specific angle relationships such as corresponding, alternate interior, and same side interior angles.

Front

If angle 2 measures 72 degrees, what is the measure of angle 4?

Back

Angle 4 measures 108 degrees because it is a same side interior angle to angle 2.
