How many points does a triangle have
Web14 dec. 2024 · I'm having difficulty finding the number of subgraphs of a triangle... the solutions of the textbook I'm using says the answer is 18, but I am counting 17 in the following way: ( 3 1) ⋅ 2 ( 0 2) + ( 3 2) ⋅ 2 ( 2 2) + ( 3 3) ⋅ 2 ( 3 2) = 17, since there are ( 0 2) = 0 edges total one can place in a graph with 1 vertex, etc. Web25 jan. 2024 · If n denotes the number of parts into which each side of the triangle is divided, I find that for n = 1, 2, 3, 4, 5, 6 the number of segments joining points is 0, 6, 18, 36, 60, 90, respectively. And from this it can be seen that, if N denotes the number of segments, then N = 3 ( n 2 − n) Hence, if each side is divided into 100 parts
