The formula for a right triangle is due to the Greek Pythagoras. It is named the Pythagorean Theorem after him. The formula is x^2+y^2=z^2, where x and y are the two legs of the right triangle and z is the hypotenuse. The hypotenuse is the side opposite the right angle. A right angle is an angle with 90 degrees. The other two angles will add up to 90 degrees because the angles in all triangles add up to 180 degrees.
By using Pythagoras' theorem for a right angle triangle.
The hypotenuse of an isosceles right triangle is 13 centimeters long. How long are its sides?
90 degree

The general formula for a triangle is Base x Height / 2. That applies quite easily for a right angle triangle.

The answer depends on what he formula is for and what other information is given.

The hypotenuse of an isosceles right triangle is 13 centimeters long. How long are its sides?
By using the formula a2+b2=c2, where a is one side of the right-angled triangle and b is the other side of the right angle triangle. C stands for the hypotenuse of the right-angled triangle. Note: this formula only works for RIGHT-ANGLED TRIANGLES!!!

Use the formula 1/2 the base * the height
The area of any triangle is1/2 of (the length of the triangle's base) times (the triangle's height).
to find the area of any triangle follow the formula: 1/2(b*h) "B" - stands for the base of the triangle "H" - stands for the height of the triangle
