Transversals

Front

What is a transversal?

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 cut by a transversal.

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 vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

What are supplementary angles?

Back

Supplementary angles are two angles whose sum is 180 degrees.

Front

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

Back

The corresponding angles are equal.

Front

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

Back

The alternate interior angles are equal.

Front

If ∠2 and ∠6 are corresponding angles, what can be inferred if the lines are parallel?

Back

If the lines are parallel, then ∠2 = ∠6.

Front

Solve for x: 3x + 5 = 26

Back

x = 7.

Front

Name the transversal for ∠7 and ∠14 in a diagram.

Back

The transversal is the line that intersects the two lines containing ∠7 and ∠14.
