WebDec 3, 2024 · This can easily be proved by the congruence of alternate interior angles. From a given vertex of a polygon with n sides, (n-3) diagonals can be drawn. Every diagonal drawn from a single vertex of a polygon creates one triangle within the polygon, except for the last diagonal, which creates two triangles. How many diagonals are drawn in a pentagon? WebMay 24, 2016 · Times 10 equals 70; each diagonal is counted twice, so the final answer is 35. Now, using combinations and such: There are ( 10 2) ("10 choose 2") pairs of vertices, which equals 45. So there are 45 line segments joining pairs of vertices. Exactly 10 of those are sides of the decagon, the others are diagonals. Answer: 35.
