WebFormula for number of diagonals on an n= sided polygon = 2n(n−3) For n=12. Number of diagonals = 212×(12−3) = 212×9. =54. WebThere are also those triangles which share two sides with the 12-gon, of which there are 12 (one for each vertex of the 12-gon--choose the two sides adjacent to the vertex). So there are 108 total excluded triangles, and thus the answer is $\binom{12}{3}-108 = 220-108 = 112$.
WebJan 11, 2024 · Sometime during the mid 1600s, a mathematician felt the need for a descriptive word for a 12-sided polygon. The word dodecagon comes from the Greek, dōdeka-, which means 12, and + -gōnon, which … Web6 years ago. So if we know that a pentagon adds up to 540 degrees, we can figure out how many degrees any sided polygon adds up to. Hexagon has 6, so we take 540+180=720. A heptagon has 7 sides, so we take the hexagon's sum of interior angles and add 180 to it getting us, 720+180=900 degrees. Same thing for an octagon, we take the 900 from ...
