Question

Determine if the following side lengths could form a triangle. Prove your answer with an inequality 28,50,22

Answer 1

Remember that

The Triangle Inequality Theorem states that the sum of any two sides of a triangle must be greater than the measure of the third side

You only need to see that the two smaller sides are greater than the largest side

In this problem

we have

28,50,22

so

28+22 > 50

50 > 50 -----> is not true

therefore

the following side lengths not form a triangle
