For any right triangle, the side lengths of the triangle can be put in the equation a2 + b2 = c2 where a, b, and c are the side
lengths. A triangle with the side lengths 3 inches, 4 inches, and 5 inches is a right triangle. Which way(s) can you substitute the values into the equation to make it true? Which variable has to match the longest side length? Why?
The longest side length is called the hypotenous of the right triangle. To find out a right triangle, u need to square each smaller sides & then square root their summation. Then, if it is same with the larger side,( which is supposed to be the hypotenous) it is a right angle.
