1) 1 in., 1in., 2in.
2) 4 in., 6 in., 9 in.
3) 9 in., 10 in., 20 in.
4) 24 in., 13 in., 10 in.

Answer 1

i know i can because it is a right triangle. i dont know about the rest. i ran out of time to think. i have to go

Answer 2

1-1-2 aint a right lol 1-1-sqrt(2) maybe

Answer 3

1-1-2 is a straight line

Answer 4

so its 1-1-2

Answer 5

9-10-20 doesnt reach the ends

Answer 6

9-10-20 is 19 and 20, they dont reach either

Answer 7

lol.... i guess if it didnt work out the first time it wont workout the next either :)

Answer 8

#2 is a triangle at least it reaches to make 3 points

Answer 9

Well you can always try the pythagorean theorem..
and take the two shortest sides and do sqrt(x^2 +y^2) and you will get the 3rd side

Answer 10

if the 2 shorts equal the long, its a straight line; if the two shorts are less than the long, you aint got nothing,

Answer 11

yeah you are right.. therefore you can eliminate that way and work with whatever is left

Answer 12

pyth only applies to right tris....

Answer 13

you can still have a tri and not have pyth :)

Answer 14

hmm.. thats right.. now im intrigued I want to figure out the answer...

Answer 15

oops amistre you are right about the 1 1 2. sorry forgot to take square root of 2 which is not equal to 2 so the first is not a triangle.
