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.

How many triangles are there in a 3X3?
In a 3x3 grid, there are a total of 16 triangles. This includes triangles formed by the intersection of the grid lines and different combinations of the grid points, including both right triangles and scalene triangles. The count considers all possible orientations and sizes of triangles that can be formed within the grid.
How many triangles on a 4x4 grid?
To determine the number of triangles in a 4x4 grid, we need to consider different types of triangles that can be formed. There are 16 small triangles formed by the grid lines themselves. Additionally, there are 18 medium triangles formed by connecting three grid points. Finally, there are 8 large triangles formed by connecting four grid points. Therefore, in total, there are 16 + 18 + 8 = 42 triangles in a 4x4 grid.
How many triangles are there in a 4 by 5 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!

How many different triangles can you find on a 3 times 3 pin geoboard?
On a 3x3 pin geoboard, you can form a total of 8 different triangles using the pins as vertices. The triangles can vary in size and orientation, and are formed by connecting any three non-collinear pins. Since the grid is small, the combinations are limited, but careful enumeration shows that there are eight distinct triangles possible.
