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

Heron created a formula to find the area of any triangle given three side lengths. It is known as Heron's Formula.

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

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.

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.

Perimeter of a triangle = (length of side #1) + (length of side #2) + (length of side #3)

The altitude of an equilateral triangle is (√3)/2*a. where 'a' is the side of the triangle. It can be just find by giving a perpendicular to the base of the triangle, the base of the triangle become a/2 and one side is a. so by applying Pythagoras theorem we will get the desired formula.

Surely you know how to find the third side of a right triangle, when you know the lengths of the other two. Find it, and then add up the lengths of the three sides to get the perimeter.

If you know two sides of a right triangle, the Pythagorean Formula lets you find the third side. Also, if you know all three sides of a triangle, you can confirm whether it is, or isn't, a right triangle.

To find the height of a triangle, you can use the formula: height = (2 * area) / base. The base of the triangle is one side of the triangle to which the height is perpendicular. The area can be calculated using different methods depending on the information available, such as using the lengths of the sides and Heron's formula or using the base and the height.
