Parallel Lines cut by a Transversal

Front

What are parallel lines?

Back

Lines in a plane that never meet and are always the same distance apart.

Front

What is a transversal?

Back

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

Front

Define alternate exterior angles.

Back

Angles that are on opposite sides of the transversal and outside the two lines.

Front

Define corresponding angles.

Back

Angles that are in the same position at each intersection where a transversal crosses two lines.

Front

What are consecutive interior angles?

Back

Angles that are on the same side of the transversal and between the two lines.

Front

What is the relationship between alternate interior angles?

Back

They are equal when the lines are parallel.

Front

If angle 1 and angle 2 are corresponding angles, what can be said about their measures?

Back

They are equal.

Front

What is the sum of the measures of consecutive interior angles when the lines are parallel?

Back

180 degrees.

Front

If angle 1 = 27°, what is the measure of angle 4 if angle 1 and angle 4 are corresponding angles?

Back

Angle 4 = 27°.

Front

What is the equation to find the value of x in the context of parallel lines and a transversal?

Back

8X - 17 + 5X + 19 = 180.
