Parallel Lines and Angles 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 are angles formed by a transversal?

Back

When a transversal crosses two parallel lines, it creates several angles, including corresponding angles, alternate interior angles, alternate exterior angles, and consecutive interior angles.

Front

Define 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

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 alternate exterior angles?

Back

Alternate exterior angles are pairs of angles that lie outside two lines and on opposite sides of a transversal.

Front

Define consecutive interior angles.

Back

Consecutive 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 alternate interior angles?

Back

If two parallel lines are cut by a transversal, then the alternate interior angles are equal.

Front

What is the relationship between parallel lines and corresponding angles?

Back

If two parallel lines are cut by a transversal, then the corresponding angles are equal.

Front

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

Back

If two parallel lines are cut by a transversal, then the consecutive interior angles are supplementary (add up to 180 degrees).

Front

How do you solve for x when given an equation involving angles?

Back

Set the equation based on the angle relationships (e.g., equal for corresponding angles) and solve for x.
