If you have the other two triangle's sides you can use a2+b2=c2
Plug in the long one for c!
Say i had the side lengths of 2 and 5. 5 is the longest side. 2*2+b2=5*5
4+b2=25
-4 -4
b2=21 do the square root of both
b=4.58
Then check it: 2*2+4.58*4.58=5*5
4+21=25 25=25 that would be correct
I took Algebra in 7th grade and I think it was a lot of fun!
But to answer your main question the formula a2+b2=c2

Who created the another formula of triangle?
Heron created a formula to find the area of any triangle given three side lengths. It is known as Heron's Formula.
Formula for a triangle?
Heron's formula to find area of triangle semi perimeter(s)=sum of all the sides of triangle/2 area of tiangle=P[s(s-first side)(s-second side)(s-third side)]1/2
What is the surface area of one side of a triangular prism?
It depends on the size of the triangular prism, but depending on the side of the prism you use the triangle area formula to find it or the rectangle area formula to find it.
What is pythagorean thorem for?
The Pythagorean theorem is used to find the length of a certain side in a right triangle. If you know the length of two sides of a right triangle, you can use the Pythagorean theorem, a2+ b2 = c2, to find the length of the other side. In the formula, c is the hypotenuse, which the longest side of the triangle.
What is the formula of a triangle in perimeter?
Perimeter of a triangle = (length of side #1) + (length of side #2) + (length of side #3)
