Transversal Angle Relationships

Front

What is the definition of 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 is the definition of 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 is the definition of 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 is the definition of Same Side Interior Angles?

Back

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

Front

What is the definition of Vertical Angles?

Back

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

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 parallel lines are cut by a transversal, what can be said about the Alternate Exterior Angles?

Back

Alternate exterior angles are equal.

Front

If two parallel lines are cut by a transversal, what can be said about the Same Side Interior Angles?

Back

Same side interior angles are supplementary (add up to 180 degrees).

Front

What is the relationship between Vertical Angles?

Back

Vertical angles are always equal.
