Given: Side lengths:
________________________________________________
" 24 in., 32 in., and 40 in " ;
________________________________________________
Divide each side length by "8" ;
24 in. / 8 = 3 in. ;
32 in. / 8 = 4 in. ; and
40 in. / 8 = 5 in. .
_________________________________________________
3 in . , 4, in, 5 in. ; is a "right triangle" ;
since: 3² + 4² = 5² ;
→ 9 + 16 = 25 ;
according to the Pythagorean theorem: " a² + b² = c² " .
