Question
If two sides of a triangle are 5 cm and 1.5 cm, the length of its third side cannot be ______.
Options
3.7 cm
4.1 cm
3.8 cm
3.4 cm
Solution
If two sides of a triangle are 5 cm and 1.5 cm, the length of its third side cannot be 3.4 cm.
Explanation:
Sum of the lengths of two sides of a triangle > length of the third side.
Here, 1.5 cm + 3.4 cm
= 4.9 cm < 5 cm
∴ Third side ≠ 3.4 cm
