Question

True or False: 2, 2, 7 are the lengths of a triangle. True False

Answer 1

The answer is false

Explanation:

2+2 > 7

4 < 7

Answer 2

False

Explanation:

If a ≤ b ≤ c are the lengths of sides of a triangle, then a + b > c.

We have a = 2, b = 2 and c = 7. Substitute:

2 + 2 = 4 → it's not greater than 7.
