Question 908857: Determine whether the triangle with the given lengths is a right triangle.
8,16,18(show work please)
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
a^2 + b^2 = c^2

8^2 + 16^2 = 18^2

64 + 256 = 324

320 = 324 ... this is close, but no cigar.

Since 320 = 324 is false, this means the triangle with sides 8,16,18 is NOT a right triangle. The 3 sides a,b,c need to make a^2 + b^2 = c^2 true (c is the longest side) for a right triangle to be possible.
