h^2 = a^2 + b^2

h = hypotenuse of the triangle

a = length of one side or the triangle

b = length of the second side of a triangle

or

h = sqrt(a^2 + b^2)

stated, “the length of the hypotenuse of a right triangle equals the square root of the sums of the squares of the sides.”

Hope that helps.

The formula is: a2* + b2* = c2*

* 2= squared for example: a2 = a SQUARED

P.S. Try this website: www. mathforum.org

where c is the hypotenuse of a right-angled triangle with the other two sides a and b.

c squared will be the hypotenuse sqaured, A and B are the two legs.

This is the formula I have my students learn
