Which of the following possibilities will form a triangle? Side = 10 cm, side = 5 cm, side = 6 cm Side = 10 cm, side = 6 cm, side = 3 cm Side = 11 cm, side = 5 cm, side = 6 cm Side = 11 cm, side = 5 cm, side = 5 cm

The sum of any two side lengths must be greater than the length of the third side...\[a+b > c\]

OpenStudy (astrophysics):

So you can do this by checking each option for example \[5 cm + 5 cm > 11 cm-----nope\]

OpenStudy (astrophysics):

Check the two shortest sides and if they are greater than the longer side than that's the one.
