Transversal Angle Relationships

Front

What are Transversal Angles?

Back

Transversal angles are angles formed when a transversal line crosses two or more lines. They include various angle relationships such as corresponding angles, alternate interior angles, and more.

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 lines and on opposite sides of a transversal. They are equal when the lines are parallel.

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. They are equal when the lines are parallel.

Front

What are 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. They are supplementary when the lines are parallel.

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. They are equal when the lines are parallel.

Front

What is the sum of angles on a straight line?

Back

The sum of angles on a straight line is 180 degrees.

Front

What is the sum of angles around a point?

Back

The sum of angles around a point is 360 degrees.

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 lines are cut by a transversal and the same side interior angles are supplementary, what can be inferred about the lines?

Back

The lines are parallel.
