grid lines are like calligraphy
Grid
Snap helps to connect lines to endpoints of other lines. Grid can be used for even spacings, measuring, but polar that can keep your lines perfectly horizontal or vertical
The correct answer is 76. There are 9 points in the grid. You can pick any 3 out of these 9 points in 9*8*7/(3*2*1) = 84 ways. However, 3 will form horizontal lines in the grid, 3 will form vertical lines in the grid, and 2 will form diagonal lines in the grid. None of these 8 triplets will form triangles, but all the rest will. So the answer is 84-8=76.
