Which of the following triangle lengths form right triangles? Select all that apply.

(7, 11, 13)
(10, 24, 26)
(12, 16, 20)
(12, 35, 37)
(13, 15, 19)

Test each set in Pythagorean theorem, since they are right triangles.

a^2+b^2=c^2

a and b are the legs, or the shorter sides, and c is the hypotenuse, or longest side

(7,11,13)

7^2+11^2=13^2

49+121=169

170=169

False

(10,24,26)

10^2+24^2=26^2

100+576=676

676=676

True

(12,16,20)

12^2+16^2=20^2

144+256=400

400=400

True

(12, 35, 37)

12^2+35^2=37^2

144+1225=1369

1369=1369

True

(13, 15, 19)

13^2+15^2=19^2

169+225=361

394=361

False
