Which set of side lengths form a right triangle?

14 m, 20 m, 25 m
3 ft, 6 ft, 5 ft
10 cm, 6 cm, 8 cm
7 cm, 8 cm, 10 cm
Help quick please!

C

Step-by-step explanation:

You know the triangle is right if the squares of the two smaller side lengths add up to the square of the largest side length, thanks to the Pythagorean Theorem: , where a and b are the legs and c is the hypotenuse.

Let's put this to the test for each answer choice:

A) --> 196 + 400 =? 625 --> 596 is NOT equal to 625, so wrong

B) --> 9 + 25 =? 36 --> 34 is NOT equal to 36, so wrong

C) --> 36 + 64 =? 100 --> 100 DOES equal 100, so correct

D) --> 49 + 64 =? 100 --> 113 is NOT equal to 100, so wrong

Thus, the answer is C.

Hope this helps!

10 cm, 6 cm, 8 cm

Step-by-step explanation:

Longest side is the hypotenuse

10² = 6² + 8²

100 = 36 + 64

100 = 100

Satisfies pythagoras theorem, hence forms a right angle triangle
