Math Teacher Question:

Answer #1
In polygons, angle between any side of the shape and a line extended from the next side is referred as Exterior Angles. All the exterior angles of the polygon add up to 360°. Each exterior angle must be 360°

Answer #2
An exterior angle is an angle that is formed when one side of a polygon extends past the point at which it meets one of its adjacent sides. All Exterior angles of a polygon DO NOT necessarily sum to 360 degrees. However, if both sides extended (in turn crossing one another). There would be 3 exterior angles created, THOSE 3 along with the Interior angle that the two lines create WILL all 4 add to 360 degrees...
