Question 76174
Does {{{a^2 + b^2 = c^2}}} where c is the longest side?
{{{5^2 + 8^2 = c^2}}}
{{{25 + 64 = 89}}
{{{c = 9}}}
{{{c^2 = 81}}}
a2 + b2 does not equal c2, not a right triangle
------------------
{{{18^2 + 24^2 = 324 + 576}}}
{{{324 + 576 = 900}}}
{{{c^2 = 30^2}}}
{{{c^2 = 900}}}
a2 + b2 = c2, so it's a right triangle
