Determine if the given side lengths could be used to form a unique triangle, many different triangles, or no triangles.
4 m, 5.1 m, 12.5 m
A. unique triangle*******
B. many different triangles
C. no triangles
Please check my work! (I'm realllly bad at this)
The sum of any two sides MUST be greater than the third side, or else no triangle is possible
let's test it:
4 m, 5.1 m, 12.5 m
Is 12.5 + 5.1 > 4 ? YES
is 12.5 + 4 > 5.1 ? YES
is 4 + 5.1 > 12.5 ? ......
So what do you think?
4 + 5.1= 9.1 making 4 + 5.1 > 12.5 incorrect thus no triangle is possible!
