Angles formed by Parallel Lines cut by Transversal Practice

Front

What are vertical angles?

Back

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

Front

Identify the relationship: ∠1 and ∠3.

Back

Vertical angles.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a straight line crosses two others.

Front

Identify the relationship: ∠7 and ∠8.

Back

Corresponding angles.

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

Identify the relationship: ∠3 and ∠6.

Back

Alternate interior angles.

Front

What are complementary angles?

Back

Complementary angles are two angles whose sum is 90 degrees.

Front

What are supplementary angles?

Back

Supplementary angles are two angles whose sum is 180 degrees.

Front

What is a transversal?

Back

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

Front

What does it mean for lines to be parallel?

Back

Parallel lines are lines in a plane that never meet; they are always the same distance apart.
