Which set of side langths form a right triangle A. 7 cmeters 8 cmeters 10 cmeters B. 10 cmeters 6 cmeters 8 cmeters C. 2 feet 6feet 5 feet D. 14 m 20m 25m

You can use the pythagorean theorem to find out if something could be a right triangle or find a missing length of said triangle

a^2 + b^2 = c^2

A. 7, 8, 10
7^2 + 8^2 = 10^2
49 + 64 = 100
113 ≠ 100

B. 10, 6, 8
6^2 + 8^2 = 10^2
36 + 64 = 100
100 = 100

C. 2, 6, 5
2^2 + 5^2 = 6^2
4 + 25 = 36
29 ≠ 36

D. 14, 20, 25
14^2 + 20^2 = 25^2
196 + 400 = 625
596 ≠ 625

The length is 23 and y because you add them together
