Unit 3 Test

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 in the same plane.

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

How do you find the value of x in angle equations?

Back

Set the equations equal to each other if the angles are equal, and solve for x.

Front

What is the sum of angles on a straight line?

Back

The sum of angles on a straight line is 180 degrees.

Front

What is the measure of vertical angles?

Back

Vertical angles are equal to each other.

Front

What is the relationship between alternate interior angles?

Back

Alternate interior angles are equal when two parallel lines are cut by a transversal.

Front

What is the equation of a horizontal line?

Back

The equation of a horizontal line is of the form y = k, where k is a constant.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the equation of a vertical line?

Back

The equation of a vertical line is of the form x = k, where k is a constant.
