QZ #14 Angles cut by Parallels and Transversal

Front

What are vertical angles?

Back

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

Front

What are corresponding angles?

Back

Corresponding angles are the angles that are in the same position at each intersection where a straight line crosses two others. They are equal when the lines are parallel.

Front

What are alternate interior angles?

Back

Alternate interior angles are the pairs of angles on opposite sides of the transversal but inside the two lines. They are equal when the lines are parallel.

Front

What are same side interior angles?

Back

Same side interior angles are the pairs of angles on the same side of the transversal and inside the two lines. They are supplementary when the lines are parallel.

Front

What do supplementary angles add up to?

Back

Front

What do complementary angles add up to?

Back

Front

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

Back

Alternate exterior angles are equal when two parallel lines are cut by a transversal.

Front

If angle 4 is 75°, what is the measure of angle 2 if lines are parallel?

Back

Angle 2 is also 75° because they are corresponding angles.

Front

What is the relationship between adjacent angles?

Back

Adjacent angles share a common side and vertex but do not overlap.

Front

If angle J is 75°, what is the measure of its supplementary angle?
