Question

Is there a triangle whose sides have lengths 12.2 cm, 6.8 cm and 6.5 cm. If not . Why?

Answer 1

yes

Explanation:

For the given sides to form a triangle.

The sum of any 2 sides must be greater than the third side.

12.2 + 6.8 = 19 > 6.5

12.2 + 6.5 = 18.7 > 6.8

6.8 + 6.5 = 13.3 > 12.2

Thus the 3 given sides form a triangle
