exterior angles
Polygon's outer turns
Exterior angles are the angles formed between a polygon's side and the extension of an adjacent side, lying outside the shape.
In geometry, the exterior angles of any convex polygon always sum to 360 degrees.
When parallel lines are cut by a transversal, exterior angles are those outside the parallel lines: The exterior angles on opposite sides of the transversal are supplementary.
- degreesUnits of measurement
- vertexPoint where edges converge
- transversalLine crossing multiple others
- parallel linesEquidistant throughout their length
