Which of the following numbers could be the sides of a right triangle. a)8,15,17. b)6,8,12 c)9,11,21 d)4,13,16

A) 8, 15, 17.

Step-by-step explanation:

Right triangle obey the Pythagorean theorem. Thus, we choose the two smaller numbers (being the cathetus) and if after applying the P. Theorem we get the biggest of each option  (the hypotenuse) that means that those numbers could be the sides of a right triangle.

The Pythagorean theorem states that:

Thus:

Option A:

→ 17 = 17 OK!

Option B:

→ 10 ≠ 12 NO

Option C:

" alt="\sqrt{202}" />" /> → ≠ 21 NO

Option D:

→ ≠ 16 NO

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.
