An external angle is the angle between the outside of one side and the extension of the adjacent line. They all add to 360o.

The external angles will. The internal angles will equal 540o.
no, the internal angles of a hexagon are 120 degrees and the external angles are 60 degrees.
Find the two varying exterior angles. For example, if they are alternating 120 degrees and 150 degrees, the external angles must be 60 degrees and 30 degrees. Since the sum of external angles for every polygon is 360, you can add 30 and 60 (the two varying external angles) = 90 degrees, then divide 360 by 90 and multiply by 2.
A heptagon has 7 sides and 7 internal angles. It also has 7 external angles. A regular heptagon has 7 equal sides
The sum of the exterior angles of any polygon is 360°. Imagine walking round any polygon until you end up where you started. You will have made a complete turn, 360°.The sum of the external angles of ANY regular polygon (or, for that matter, any convex polygon) is 360 degrees.The sum of the internal angles is always equal to 180 (n-2) where n is the number of angles.
