Transversal Angle Relationships

Front

What is a Transversal?

Back

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

Front

What are Corresponding Angles?

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a transversal crosses two lines.

Front

What are Alternate Interior Angles?

Back

Alternate interior angles are pairs of angles that lie between two lines and on opposite sides of a transversal.

Front

What are Alternate Exterior Angles?

Back

Alternate exterior angles are pairs of angles that lie outside two lines and on opposite sides of a transversal.

Front

What are Consecutive Interior Angles?

Back

Consecutive interior angles are pairs of angles that lie between two lines and on the same side of a transversal.

Front

What is the relationship between Corresponding Angles when lines are parallel?

Back

When two parallel lines are cut by a transversal, corresponding angles are equal.

Front

What is the relationship between Alternate Interior Angles when lines are parallel?

Back

When two parallel lines are cut by a transversal, alternate interior angles are equal.

Front

What is the relationship between Alternate Exterior Angles when lines are parallel?

Back

When two parallel lines are cut by a transversal, alternate exterior angles are equal.

Front

What is the relationship between Consecutive Interior Angles when lines are parallel?

Back

When two parallel lines are cut by a transversal, consecutive interior angles are supplementary (add up to 180 degrees).

Front

How do you identify Corresponding Angles in a transversal situation?

Back

Look for angles that are in the same position relative to the two lines and the transversal.
