32+ Decagon Angles Pictures
32+ Decagon Angles Pictures. Sum of interior angles = (n−2) × 180°. To find the exterior angle of a regular decagon, we use the fact that the exterior angle forms a linear pair with the interior angle, so in general it is given.
Find the exterior angle sums, one exterior angle at each vertex, of a convex nonagon.
A decagon has 10 sides, and 10 angles. If we draw a perpendicular ao on bc, we will see that the perpendicular. A regular decagon, a decagon whose 10 sides are all equal in length, has interior angles that each contain 144 degrees. Regular decagons have sides of equal length and interior angles of 144 degrees.
