How many diagonals does an pentadecagon have
WebA polygon of n sides has n vertices. By joining any two vertices of a polygon, we obtain either a side or a diagonal of the polygon. Number of line segments obtained by joining the vertices of an n sided polygon taken two at a time = Number of ways of selecting 2 out of n =n C 2= 2n(n−1) Out of these lines, n lines are the sides of the polygon. WebDec 1, 2024 · A pentagon is any polygon that has five sides and five angles. The root of the word pentagon is “penta” which comes from the Greek word for five. “Gon” comes from the Greek word for angle. So, if you put the two words together, you get “five angles,” which corresponds to how many angles are in the shape. As I just mentioned, in ...
