Many different types, but mostly equilateral triangles.
u can make none.
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.
There are 6 triangles in an octagon
Infinitely many.
depends on what size triangles and what kind of triangles?
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.

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 3 triangles in a pentagon
There are 6 triangles in an octagon
10 triangles
10 triangles make a decagon
27 triangles make up an Icosihenagon
