3.2 Extra Credit Angles Pairs in 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

Define corresponding angles.

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a straight line crosses two others.

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that lie between two lines and on opposite sides of a transversal.

Front

What are alternate exterior angles?

Back

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

Front

What are consecutive interior angles?

Back

Consecutive interior angles are pairs of angles that lie between two lines and on the same side of a transversal.

Front

What is the relationship between angles 2 and 4 if they are vertical?

Back

If angles 2 and 4 are vertical angles, they are equal in measure.

Front

If angle 5 and angle 6 are vertical angles, what can be said about their measures?

Back

If angle 5 and angle 6 are vertical angles, then their measures are equal.

Front

What is the relationship of angles s and y if they are alternate exterior angles?

Back

If angles s and y are alternate exterior angles, they are equal in measure.

Front

If angle 7 and angle 5 are corresponding angles, what can be said about their measures?

Back

If angle 7 and angle 5 are corresponding angles, then their measures are equal.

Front

What is the definition of transversal in geometry?

Back

A transversal is a line that intersects two or more lines at different points.
