In a right angled triangle, with sides (legs) a and b, and hypotenuse c, then
c² = a²+b².
The square of the hypotenuse is the sum of the squares of the legs.
A "3,4,5" triangle has a right angle in it, so the formula should work.
Yes, it works!!!
Apply the Pythagorean Theorem: If you know any two of the sides in a right triangle, you can find the dimensions for the missing side using the Pythagorean Theorem.
In a right triangle you know
the legs are 24 and 18 units long.
