A triangle has sides with lengths of 8 inches, 15 inches, and 17 inches. Is it a right triangle?

Yes

Step-by-step explanation:

Pythageron Theorem:

a^2+b^2=c^2

a and b are the legs, or the 2 shorter lengths. (8 and 15)

c is the hypotenuse, or the longest length (17)

8^2+15^2=17^2

64+225=289

289=289

Since the statement is true, it is a right triangle

Hope this helps! :)
