4.1 - 4.3 Test Parallel Lines

Front

What are Vertical Angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

What is the relationship between Complementary Angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

What is the relationship between Supplementary Angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

Define Alternate Interior Angles.

Back

Alternate interior angles are pairs of angles on opposite sides of a transversal but inside the two lines.

Front

Define Alternate Exterior Angles.

Back

Alternate exterior angles are pairs of angles on opposite sides of a transversal but outside the two lines.

Front

What are Corresponding Angles?

Back

Corresponding angles are pairs of angles that are in the same position on two different lines cut by a transversal.

Front

What are Consecutive Interior Angles?

Back

Consecutive interior angles are pairs of angles on the same side of the transversal and inside the two lines.

Front

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

Back

Corresponding angles are equal.

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

If two angles are supplementary and one angle measures 75 degrees, what is the measure of the other angle?

Back

The other angle measures 105 degrees.
