What Does An Adjacent Exterior Mean?

The exterior angle of a triangle is the angle formed by one side and its adjacent side when any side of the triangle is extended. Congruent angles, even those not identically presented, show the same “openness” between the two rays, line segments, or lines that form them. Consecutive exterior angles are pairs of angles on one side of the transversal but outside the two lines.

There are three exterior angles in a triangle, and the sum of the exterior angles is always equal. For any polygon, the exterior angle of a polygon is formed by extending one of its sides and its adjacent side at the vertex. The interior angle of a polygon is always supplementary to the exterior angle at that vertex.

Exterior angles are parallel to the inner angles of a polygon but lie on the outside of it. An adjacent interior angle is the angle who shares a side and a vertex with a given exterior angle. The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles of the triangle. Alternate exterior angles are formed when a transversal intersects two or more parallel lines at distinct points.

In summary, exterior angles are angles found outside or external to any geometric shape, such as a triangle or a polygon. They are formed by extending one side and an adjacent side of the triangle.
