WebMar 26, 2024 · Along with nine sides, a nonagon has nine vertices and 27 possible diagonals that can be drawn from vertex to vertex. How many sides does a hexagon have? Hexagon: 6 Sides A hexagon has six sides and six vertices, or points. The interior angles of a hexagon add up to 720 degrees. WebMay 24, 2016 · A diagonal joins a vertex to one of the vertices that do not include that vertex itself and the immediately adjacent vertices. So: for each vertex there are seven diagonals. Times 10 equals 70; each diagonal is counted twice, so the final answer is 35.

WebA Polygon is a closed figure made up of line segments (not curves) in a two-dimensional plane. Polygon is the combination of two words, i.e. poly (means many) and gon (means sides). A minimum of three line segments is required to connect end to end, to make a closed figure. Thus a polygon with a minimum of three sides is known as Triangle and ...
WebWe can also calculate the number of diagonals by using the formula n(n - 3)/2 where n is the number of sides of a polygon. For a heptagon, the value of n is 7.
