what is the formula for figuring out if a triangle is a right triangle by adding up the lengths of the sides?

Answer 1

The sum of the squares of the sides equals the square of the hypotenuse: a^2 + b^2 = c^2
The Pythagorean Theorem.

Answer 2

Well if it is a right triangle then A^2 + B^2 = C^2.

It is called the pythagorean theorem.

Answer 3

The Pythagorean Theorem:

a^2 + b^2 = c^2

Answer 4

If it's a right triangle, a-squared plus b-squared = c-squared
with a being one of the short sides, b being the other short side, and c being the longest side. If they don't turn out equaling out right when you square them and add things, then it's not a right triangle. But if it works, then it is.

Answer 5

You can find out just by looking at it, you don't need a formula. A right angle is 90 degree angle. The letter L forms a 90 degree angle.

Answer 6

if i undesrstand what u sayin than
i triangle is a right triangle if c^2=a^2+b^2 c-the hypotenuse

Answer 7

the square on the hypotenuse is equal to the square on the other two sides ?
