How many triangles are in the 4 by 4 by 4 triangular grid?
30 triangles (1 to the power of 2) + (2^2) + (3^2) + (4^2) = 1 + 4 + 9 + 16 = 30
What are the 3 types of triangles?

Does an equilateral triangle has 0 or 1 or 2 or 3 sides?
ALL triangles have three sides !
How many triangles are there whose length of sides are integers and whose perimeters are equal to 5?
Only two: -- 1, 1, 3 -- 1, 2, 2

Equilateral triangles have 3 equal sides whereas isosceles triangles have only 2 equal sides
What is ratio of 2 circles and 3 triangles?

How many triangles are in the 4 by 4 by 4 triangular grid?
30 triangles (1 to the power of 2) + (2^2) + (3^2) + (4^2) = 1 + 4 + 9 + 16 = 30
What is the ratio of 2 circles and 3 triangles?
The ratio of two circles to three triangles is not a straightforward comparison as circles and triangles are different shapes. However, if we are comparing the areas of two circles to the combined areas of three triangles, we would need to calculate the area of each shape using their respective formulas (πr^2 for circles and 1/2 base x height for triangles) and then compare the total areas. The ratio would then be the total area of the circles divided by the total area of the triangles.

What are the 3 types of triangles?

What is the recurrence relation of the number of triangles inside a triangle?
Well, it just so happens that I figured this out for whoever was wondering... When n is even, and n+1 is odd (obviously) Sn+1 = Sn + (n+2)(3n+2)/4 When n is odd, and n+1 is even (obviously) Sn+1 = Sn + (n+1)(3n+5)/4 These formulas are for the total triangles in something that looks like this... /\ /_\ /\ /\ /_\ /_\ /\ /\ /\ /_\ /_\ /_\ This triangle has n=3 and has 13 total triangles. The general formula for total triangles is hard to find. And because this question doesn't ask for the general solution for any n, I won't post it. It is really fun to find though... The solution is shown below... Total Number of triangles = (n*n) + ( (n) * (n-1) * (4n+1) / 2 ) where n = (k+1) /2. K is the number of triangles on the each side. In the above example k is 3. k = 1 -> Total Triangles = 1 k = 2 -> Total Triangles = 4.875 ~ 5 k = 3 -> Total Triangles = 13 k = 4 -> Total Triangles = 26.875 ~ 27 k = 5 -> Total Triangles = 48 k = 6 -> Total Triangles = 77.875 ~ 78 and so on....

How many triangles and rectangles are in a triangular prism?
2 triangles and 3 rectangles(:
How many triangles are there whose length of sides are integers and whose perimeters are equal to 5?
Only two: -- 1, 1, 3 -- 1, 2, 2
Does a triangle have 2 congruent sides?
Some, but not all. Triangles with 2 congruent sides are called isoceles triangles. Triangles with 3 congruent sides are called equilateral triangles.

Three triangles
What kind of triangles have 2 sides?
None because all triangles have 3 sides
