Alternate interior and exterior angles definition. Alternate Exterior Angles Explanation Examples In Geometry there is a special kind of angles known as alternate angles. Start studying Alternate Interior Exterior and Consecutive Interior Angles. Also like with interior angles the above exterior angles are equal when a transversal line crosses 2 parallel lines.

Called also alternate interior angle. Corresponding angles are just one type of angle pair. The theorem says that when the lines are parallel the alternate interior angles are equal.

The angles that are formed on opposite sides of the transversal and inside the two lines are alternate interior angles. Alternate interior angles are formed when a transversal passes through two lines. Angles 2 and 7 are ALTERNATE and angles 1 and 8 are ALTERNATE.

What are the alternate exterior angles. Alternate exterior angles are angles that are on opposite sides of the transversal and outside the two lines. Here are lines T R and I P which would definitely cross somewhere in the distance.

To help you remember. One of a pair of angles inside the two intersected lines. If two parallel lines are transected by a third line the angles which are on the same side of the third line and on corresponding sides of the parallel lines are called corresponding angles.

When the two lines are parallel Alternate Exterior Angles are equal. When two lines are crossed by another line the Transversal a pair of angles on the outer side of those two lines but on opposite sides of the transversal are called Alternate Exterior Angles. These angles are located at the inside corners of the intersections and are on opposite sides of the transversal.
