## Alternate exterior angles

### the pair of angles that are formed on the outer side of the parallel lines but on the opposite side of the transversal

Alternate exterior angles are formed when two parallel lines are intersected by a third line. An alternate exterior angle is an angle that is located outside the two parallel lines and on the opposite side of the transversal line compared to the intersected line. Here are some points to consider:

– Alternate exterior angles are always congruent. This means that they have the same measure or degree value.

– They are called alternate because they are found on alternating sides of the transversal line.

– Alternate exterior angles can be used to prove that two lines are parallel. If the alternate exterior angles are congruent, this indicates that the two lines are parallel.

– The sum of the measures of the two alternate exterior angles is 180 degrees. For example, if one angle has a measure of 100 degrees, the other angle will have a measure of 80 degrees, since 100 + 80 = 180.

– Alternate exterior angles are an important concept in geometry and are used in various applications, including architecture, engineering, and physics.

It is important to note that alternate exterior angles are different from alternate interior angles, which are located inside the two parallel lines on the opposite sides of the transversal line.
