Two sides of a triangle measure 4 cm and 9 cm. Determine which of the following choices cannot be the measure of the third side.(1 point)
Responses
- 11 cm
- 13 cm
- 15 cm
Using the triangle inequality theorem, we can determine which sides cannot be the measure of the third side:
- 11 cm: This can be the measure of the third side because 4 + 9 > 11.
- 13 cm: This can be the measure of the third side because 4 + 9 > 13.
- 15 cm: This cannot be the measure of the third side because 4 + 9 < 15.
