Angle Relationships with Parallel Lines and Transversals

Front

What are Alternate Interior Angles?

Back

Angles that lie between two parallel lines and on opposite sides of a transversal.

Front

If \( \angle 5 \) and \( \angle 4 \) are Alternate Interior Angles, what are the other Alternate Interior Angles?

Back

\( \angle 3 \) and \( \angle 6 \)

Front

What is a transversal?

Back

A line that intersects two or more lines.

Front

What are Corresponding Angles?

Back

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

Front

If \( \angle 1 \) and \( \angle 8 \) are Corresponding Angles, what is the relationship between them?

Back

They are equal.

Front

What are Vertical Angles?

Back

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

Front

If \( \angle 3 \) and \( \angle 7 \) are Corresponding Angles, what can be said about their measures?

Back

They are equal.

Front

What is the relationship between Alternate Exterior Angles?

Back

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

Front

What are Supplementary Angles?

Back

Two angles whose measures add up to 180 degrees.

Front

If \( \angle 4 \) and \( \angle 5 \) are Supplementary, what is the equation that represents their relationship?

Back

\( \angle 4 + \angle 5 = 180^{\circ} \)
