Question

. Is a triangle with sides of length 6 ft., 21 ft., 23 ft. a right triangle? Explain

Answer 1

use Pythagorean theorem

Answer 2

Just plug the numbers into the pythagorean theorem, if the two numbers equal each other, then yes, if not, no.

a^2 + b^2 = c^2
where a = 6, b = 21, and c = 23
so
6^2 + 21^2 = 23^2
36 + 441 = 529
447 does not equal 529

No, it is not a right triangle
