(b) No, it is NOT possible

• 5, 7, 10

• 11, 21, 16

• 4, 9, 15

Answer explanation

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

YES:

11, 21, 16

5, 7, 10

NO:

4, 9, 15. This is because 4+9=13 which is NOT greater than the third side, 15.

Find the range of possible measures for the third side if two sides of a triangle are 9 and 5.
