28, 45, 53
B.
16, 63, 65
C.
13, 84, 85
D.

Answer 1

For each choice, square each of the three numbers.
Then add the two smaller squares.
If the sum of the two smaller squares equals the third square, it's a Pythagorean triple.

Answer 2

Do you know how to find out? Use the Pythagorean theorem \[\Large a^2 + b^2 = c^2\]and check if it's true.

Answer 3

A Pythagorean triple is a set of three numbers that satisfies the Pythagorean equation:

\(a^2 + b^2 = c^2 \)
