An octagon is made up from six triangles each containing 180 degrees.
45 degrees/angle for a regular octagon.350/8=45.
An octagon.
An octagon has eight angles. Each internal angle in a regular octagon measures 135 degrees, and the sum of all internal angles in an octagon is 1,080 degrees. Therefore, it has eight angles, each formed by the intersection of two sides.
You will have to define who "they" is.
It is: 135 degrees
20 diagonals in Octagan. For n-sided polygon, no of diagonals = (n choose 2 ) - n = 8C2 - 8 = 28 - 8 = 20
a crescent has 19 sides
