Parallel Lines Cut by a Transversal

Front

Vocabulary: Angles that are across from each other

Back

Vertical angles are angles that are opposite each other when two lines intersect.

Front

If Angle 1 = 27° Find the measure of angle 4

Back

Angle 4 = 27° (Vertical angles are equal).

Front

What is the relationship of the angles formed by parallel lines cut by a transversal?

Back

Alternate Interior angles are angles that lie between the two lines and on opposite sides of the transversal.

Front

What is the value of x if Angle 1 = 27° and Angle 2 is a corresponding angle?

Back

x = 27° (Corresponding angles are equal).

Front

Which is a pair of corresponding angles?

Back

∠4 and ∠8 are corresponding angles.

Front

Define corresponding angles.

Back

Corresponding angles are angles that are in the same position on two parallel lines in relation to a transversal.

Front

What are alternate exterior angles?

Back

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

Front

If two parallel lines are cut by a transversal, what can be said about the alternate interior angles?

Back

Alternate interior angles are equal.

Front

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

Back

The sum of the interior angles on the same side of the transversal is 180°.

Front

If Angle 3 = 72°, what is the measure of Angle 5?

Back

Angle 5 = 72° (Alternate interior angles are equal).
