Question

Can you form a right triangle with the three lengths given? Why or why not? 4mi, 5mi, 6mi

Answer 1

yes it's possible. sum of square of 4 and 5 is equal to the square of 6.

Answer 2

A right triangle must satisfy this equation: a^2 + b^2 = c^2

a= shortest length
b=medium length
c=the longest length

a triangle with sides 4,5,6 will satisfy not this equation because:
4^2 + 5^2 ≠ 6^2
16+25 = 41

41 ≠ 36

so the answer is C.

Hope this helps.
