Parallel Lines Cut By a Transversal FLASHCARD

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

What are corresponding angles?

Back

Angles that are in the same position on two 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 lines.

Front

What are alternate exterior angles?

Back

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

Front

What are vertical angles?

Back

Angles that are opposite each other when two lines intersect.

Front

If angle 1 = 27°, what is angle 4 if they are corresponding angles?

Back

Angle 4 = 27°.

Front

If angle 1 = 27°, what is angle 3 if they are alternate interior angles?

Back

Angle 3 = 153°.

Front

If angle D = 116°, what is the measure of angle C if they are supplementary?

Back

Angle C = 64°.

Front

If angle 1 = 80° and angle 2 is its corresponding angle, what is angle 2?

Back

Angle 2 = 80°.
