Parallel Lines and Transversals

Front

What are parallel lines?

Back

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

Front

What is a transversal?

Back

A transversal is a line that crosses at least two other lines.

Front

What are corresponding angles?

Back

Corresponding angles are angles that are in the same position on two different parallel lines cut by a transversal.

Front

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

Back

Alternate interior angles are equal.

Front

What are complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

What are supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

If angle 2 is 70 degrees, what is the measure of angle 1 if they are same-side interior angles?

Back

Angle 1 is 110 degrees.

Front

Solve for x: 2x + 10 = 70. What is x?

Back

x = 30.

Front

If angle A is 44 degrees, what is the measure of its complement?

Back

The complement of angle A is 46 degrees.

Front

Identify the corresponding angles if angle 4 is 60 degrees. What is angle 8?

Back

Angle 8 is also 60 degrees.
