It’s THEOREM

I think you mean PYTHAGOREAN – which is the relationship between the sides of a right angled triangle

Sum of squares on shortest sides = square of longest

If you ever watch the original “Wizard of Oz”, listen when the Scarecrow gets a brain. His first words are to state the Pythagorean Theorem, except that he gets it wrong.

a^2 + b^2 = c^2

In english, the square of the hypoteneuse is equal to the sum of the squares of the other two sides.

In any right triangle, the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares whose sides are the two legs (the two sides other than the hypotenuse).

otherwise:

a (squared) plus b(squared)=c(squared)

In any right triangle, the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares whose sides are the two legs (the two sides other than the hypotenuse).

otherwise:

a (squared) plus b(squared)=c(squared)

A^2+b^2=c^2

the two shorter sides squared = the square of the longest side
