No, it will not.
This is due to the law of a triange. Any two sides must be LARGER than the third.
ie, a + b > c; a + c > b; b + c > c
See, let 4 = side a, 9 = side b, and 5 = side c
4 + 9 > 5 = correct
4+5 > 9 = false
5+9 > 4 = correct
For it to be a triangle, all three of those equations must be correct.
if you were to attempt to make a triangle with these three lines, it would end up just a straight line nine units long.

To find whether 3 given sides can be a triangle, you must add each combination of 2 of the sides and see whether it is greater than the 3rd side.
4+9 is greater than 5 (it works)
9+5 is greater than 4 (it works)
4+5 is equal to 9 not greather (doesn't work) <-- (this is why you can't stop at doing just 1 or 2 combinations.)
No, these given lengths cannot form a triangle.

No, the values of two smaller add up to 9, which would create a straight line. When added, the two smaller lengths should be more than the longest length. So, 5, 9, and 5 could form a triangle, but lengths above could not.

They won't make a triangle because 4+5 = 9.
In a sense, the only closed shape they could make is a triangle with an angle of 180 degrees between the 4 and 5 and 0 degrees between the 9 and 4 and the 9 and 5. This is basically a straight line:

No.
The two legs of length 4 and 5 add up to 9, so any attempt to make a triangle will only make a line segment of length 9.

No. the longest side must be shorter than the sum of the other 2 sides. 9=4+5

No, it won't.
Any given two sides of a triangle must add up together to be more than the third side. It cant be equal or less, it must be more.
4+5=9, thats equal, not more.

No, the values cannot make a triangle. The sum of the length of every two sides must exceed the length of the third side.

no. For a triangle to exist, the longest side must be greater than the sum of the length of the two shorter sides.

nope they r not goin to make a tringale
since the sum of the two sides must be greater
lik it could be said that 6+5=11ie 6, 5, 9 could be considered
