Question

Determine whether it is possible to form a triangle with the given side lengths.

AB= 4 cm, BC= 6 cm, AC= 12 cm

Answer 1

• No, not possible

Explanation:

According to triangle inequality, any side is less than the sum of the other two:

• AB + BC > AC

We see contradiction with above when values substituted:

• 4 + 6 = 10 < 12

It means we can't form a triangle with given sides
