A right triangle has legnths that have a special relationship to each other
if you have legs legnth a and b and hypotonuse legnth c
a^2+b^2=c^2 yeilds a true statement
so the hypotonuse is normally the longest side so 41 cm is the hypotonuse
c=41
a=7
b=40
subsitute
7^2+40^2=41^2
49+1600=1681
1649=1681
false
this is not a right triangle
