What kind of triangles make up a pyramid?
Many different types, but mostly equilateral triangles.
How many different triangles can you make from a set of three side lengths?
u can make none.
How many triangles are there in a three by three grid?
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 make an octagon?
There are 6 triangles in an octagon
How many different triangles are there that have a perimeter of 10?

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!
