Angle Relationships

Front

What are Vertical Angles?

Back

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

Front

What are Alternate Interior Angles?

Back

Alternate interior angles are pairs of angles that lie between two parallel lines and on opposite sides of a transversal. They are equal in measure.

Front

What are Alternate Exterior Angles?

Back

Alternate exterior angles are pairs of angles that lie outside two parallel lines and on opposite sides of a transversal. They are equal in measure.

Front

What are Corresponding Angles?

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines in relation to a transversal. They are equal in measure.

Front

What is a Transversal?

Back

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

Front

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

Back

The alternate interior angles are equal.

Front

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

Back

The corresponding angles are equal.

Front

If two lines intersect, what can be said about the vertical angles formed?

Back

The vertical angles are equal.

Front

What is the relationship between alternate exterior angles when two parallel lines are cut by a transversal?

Back

The alternate exterior angles are equal.

Front

How can you identify corresponding angles?

Back

Corresponding angles are located in the same relative position at each intersection of the transversal with the two lines.
