WebA regular decagon has 10 vertices and 35 diagonals. The diagonals of a decagon are found by using the formula n (n-3) ÷ 2, where n is a number of sides that is 10. So, 10 (10-3) ÷ 2 = 35. What are the Exterior Angles of a Regular Decagon? The exterior angles of a decagon are the outside angles formed by two sides joined by one vertex of a decagon. WebNonagon.
