Unit 3 Parallel and Perpendicular Lines Review

Front

What are parallel lines?

Back

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

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 same side interior angles?

Back

Same side 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 parallel lines and corresponding angles?

Back

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

Front

What is the relationship between parallel lines and alternate interior angles?

Back

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

Front

What is the relationship between parallel lines and same side interior angles?

Back

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

Front

If angle 4 is 88 degrees, what is the measure of angle 5?

Back

Angle 5 is also 88 degrees because they are corresponding angles.

Front

What is the measure of angle b if it is the same side interior angle to angle 4 which is 88 degrees?

Back

Angle b is 92 degrees because same side interior angles are supplementary.
