Six of them
regular hexagon has six sides of equal length, each couple intersecting to form a vertex of which there are six. A polygon has six internal angles of equal measure and has six external angles of equal measure.External angles= angles on the outsideInterior angles= angles on the inside(of the shape.)For a hexagon you'd do 360/6 (because it has 6 corners/angles) which = 60, that is the exterior angle, to find the interior angle you'd take 60 away from 180 because that's how many degrees are on a straight line, which would make it 120 degrees
120 Degrees A hexagon, or a "6-gon," which has six sides has this sum of interior angles: (6-2)180=720° So, each individual angle is: 720/6=120°
