Question

(1 point)

Answer 1

The third side must be greater than the difference of the other two sides and less than the sum of the other two sides.

Given sides: 4 cm and 9 cm

4 + 9 = 13
9 - 4 = 5

Therefore, the third side must be greater than 5 cm and less than 13 cm.

Choices:
A) 2 cm - This cannot be the measure of the third side, as it is less than 5 cm.
B) 6 cm - This can be the measure of the third side, as it is between 5 cm and 13 cm.
C) 12 cm - This can be the measure of the third side, as it is between 5 cm and 13 cm.
