If the measures of two sides of a triangle are 3 feet and 7 feet, which of the following is a possible whole number measure for the third side? A. 3 B. 4 C. 5 D. 10
As always, I am not looking for the answer I just want to know how to find the answer. @Loser66
what do you think?

I'm thinking 10.
yup, guess or you have a logic for this answer?
I knew it couldn't be the first two, and the second would make it flat, so 10 just made sense.
let's wait for others' idea. I am with you so far. but we may be wrong, hihihi
What would the skinniest triangle (smallest vertex between the two sides you have) be? What would the fattest (largest vertex) one be? They determine the third side's limits.
oh, I am thinking of douglaswinslowcooper's idea, his logic is good too. think of this |dw:1387057049907:dw|
