WebSep 8, 2024 · A square has four vertices. No three of which are colinear. Therefore those vertices form \dbinom {4} {3}=4 (34) = 4 different triangles. SEE HERE Now add the two diagonals and we get a fifth point. But that means of the \dbinom {5} {3}=10 (35) = 10 there are two triples that are colliear.

WebOct 27, 2015 · The total number of diagonals is then: r 1 + r 2 + r 3 + r 4 + r 5 = r 1 + 12 − d 3 − d 5 ≤ 17. and we can only have equality if r 1 = 5 and d 3 = d 5 = 0. However, if r 1 = 5 and r 2 = 1, r 3 cannot be 5 because the diagonal in row 2 cannot have its lower vertex on the boundary of the array of squares.
