Which side lengths form a right triangle
aleksandrvk [35]

Answer:

A and C

Step-by-step explanation:

  • A right triangle consists of two legs and a hypotenuse.
  • To find hypotenuse, we use The Pythagorean Theorem
  • The Pythagorean Theorem = {a}^{2}  +  {b}^{2}  =  {c}^{2}
  • two legs meet at a 90° angle and the hypotenuse is the longest side

3 - 4 - 5

6 - 8 - 10

7 - 24 - 25

5 - 12 - 13

are some basic right triangle

(about more, look picture)

<em><u>Just use hypotenuse formula :</u></em>

3 x 3 = 9

4 x 3 = 12

5 x 3 = 15

Option C is correct

{5}^{2}  +  { \sqrt{6} }^{2}  =  { \sqrt{31} }^{2}

Option A is correct

{5}^{2}  +  {5}^{2}  =  { \sqrt{50} }^{2}

But B isn't correct

Hope this helps ^-^
