3.1 Identifying Angles Given Two Lines and a Transversal

Front

What is a transversal in geometry?

Back

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

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on different parallel lines when a transversal crosses them.

Front

Define 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 consecutive interior angles?

Back

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

Front

If two parallel lines are cut by a transversal, what can be said about the corresponding angles?

Back

Corresponding angles are equal.

Front

What is the relationship between alternate interior angles when two parallel lines are cut by a transversal?

Back

Alternate interior angles are equal.

Front

How do you identify consecutive interior angles?

Back

Consecutive interior angles are found on the same side of the transversal and between the two lines.

Front

What is the sum of the measures of consecutive interior angles?

Back

The sum of the measures of consecutive interior angles is 180 degrees.

Front

If angle 3 and angle 5 are alternate interior angles, what can be concluded if they are equal?

Back

If angle 3 and angle 5 are equal, then the lines cut by the transversal are parallel.

Front

What are the properties of corresponding angles when two lines are parallel?

Back

Corresponding angles are equal when two lines are parallel.
