Which of the following are measurements of the sides of a right triangle? a. 3,4,5 b. 28,12 c. 17,14,6 d. all of the above

A right triangle has the 3/4/5 rule, which is pythagorean theorum.
A^2 (A squared) + B^2 (B squared) = C^2 (C squared).
You can test this.
Let's try the first option, A.
3^2 (A) + 4^2 (B) = 5^2 (C).
3^2 = 9, B^2 = 16, C^2 = 25.
9 + 16 = 25.
A.) is the correct answer.

A. Only A follows the Pythagorean theorem  A^2 +B^2 =C^2
C = hypotenuse
A and B = other sides( doesn't matter which)
