Defining Interior and Exterior Angles

This video tutorial explains the concepts of interior and exterior angles, including alternate interior and exterior angles, and corresponding angles. It discusses how these angles are formed when a line intersects two other lines, which may or may not be parallel. The video also covers the conditions under which these angles are congruent, particularly when the lines are parallel, and provides naming conventions used in geometry to describe these angles.

How many angles are formed when two lines intersect with another line?

• Four angles

• Six angles

• Eight angles

• Ten angles
