9 squares = 18 triangles
* * * * *
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.
you can make 76 different triangles on a 3x3 grid

Three triangles.
A triangle has three sides, so six triangles have 6 * 3 = 18 sides altogether.
You can make any triangle, quadrilateral or pentagon with three suitable triangles.
depends on what size triangles and what kind of triangles?
you can make 76 different triangles on a 3x3 grid
If its a 4 by 5 grid, there are 20 squares because 4 times 5 =20 20 by 2 is 40 so there are 40 triangles because there are 2 triangles that fit into each square. Hope this helps!

There are two triangles in three verticals. This is used in math.
30 triangles (1 to the power of 2) + (2^2) + (3^2) + (4^2) = 1 + 4 + 9 + 16 = 30
