Same Side Exterior Angles:
In geometry, same side exterior angles refer to a pair of angles that are located on the same side of a transversal line crossing through two parallel lines

Same Side Exterior Angles:
In geometry, same side exterior angles refer to a pair of angles that are located on the same side of a transversal line crossing through two parallel lines. The transversal line intersects one of the parallel lines at one point and the other parallel line at another point.

To identify same side exterior angles, we can imagine two parallel lines and a transversal line passing through them. Any two angles that are both outside the parallel lines and on the same side of the transversal are considered same side exterior angles.

Properties of Same Side Exterior Angles:
1. Same side exterior angles are supplementary: The sum of the measures of any two same side exterior angles is always 180 degrees. In other words, the angles are supplementary.

2. Same side exterior angles are equal when the parallel lines are intersected by a transversal: If the parallel lines are intersected by a transversal and the same side exterior angles are formed, then each pair of same side exterior angles will have equal measures.

3. Identifying same side exterior angles helps to establish congruence or similarity: Same side exterior angles are helpful in proving two figures congruent or similar by establishing relationships between the angles of the figures. By using the properties of same side exterior angles, we can identify congruent angles and make conclusions about the similarity of the figures.

It is important to note that same side exterior angles should not be confused with same side interior angles, which are located inside the parallel lines and on the same side of the transversal.

Overall, understanding same side exterior angles helps in analyzing the relationships between angles and parallel lines, and it is a fundamental concept in geometry.
