11.23 Parallel Lines with 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 crosses at least two other lines in the same plane.

Front

What are corresponding angles?

Back

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

Front

What are alternate interior angles?

Back

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

Front

What are alternate exterior angles?

Back

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

Front

What is the sum of the interior angles on the same side of the transversal?

Back

They are supplementary, meaning they add up to 180 degrees.

Front

If angle 1 is 44 degrees, what is the measure of angle 2 if angle 1 and angle 2 are corresponding angles?

Back

Angle 2 is also 44 degrees.

Front

If angle 3 is 60 degrees, what is the measure of angle 5 if angle 3 and angle 5 are alternate interior angles?

Back

Angle 5 is also 60 degrees.

Front

What is the equation to find the value of x if angle 4 and angle 5 are supplementary?

Back

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

Front

What is the equation to solve for x if angle 6 and angle 7 are corresponding angles?

Back

12X - 19 + 4X + 1 = 180.
