WILL MARK BRAINLIST Which set of side lengths below will NOT form a right triangle?

A. 3 ft, 4 ft, 5 ft
B. 8 m, 15 m, 17 m
C. 1 in, 2 in, 3 in
D. All sets of side lengths above will form a right triangle.

C. 1 in, 2 in, 3 in

if you think about it- the 3inch side will be as long as the other 2 sides put together. it wouldn't form a triangle at all- just one line on top of the other 2.

f

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
