Q. If the lengths of two sides of a triangle are 8 cm and 6 cm, what is the range of possible lengths for the third side?
A.
2 cm to 14 cm
B.
2 cm to 10 cm
C.
4 cm to 14 cm
D.
4 cm to 10 cm
Solution
The length of the third side must be greater than the difference of the other two sides and less than their sum: |8 - 6| < third side < 8 + 6, which gives 2 < third side < 14.
