A^2 , b^2 , c^2 represent

whatever you want them to represent. On right triangles, abc often (but not always) represents a and b are legs, and c is the hypotenuse. But that is not a LAW. I could draw a right triangle labeling the legs gamma, lemma, and the hypotenuse Iota.

If you are using a right triangle with a,b,c, then c^2=a^2+b^2

What Is a pythgorean Theorem ?

A^2, B^2, and C^2 represent the squares of the values of A, B, and C respectively.

To calculate the square of a number, you simply need to multiply that number by itself. For example, A^2 is calculated by multiplying the value of A with itself.

So, if you know the values of A, B, and C, you can find A^2, B^2, and C^2 by multiplying each of them with themselves.

For example, if A = 3, B = 5, and C = 2, then
A^2 = 3 * 3 = 9
B^2 = 5 * 5 = 25
C^2 = 2 * 2 = 4

Therefore, A^2 = 9, B^2 = 25, and C^2 = 4.
