Question

Which of the following cannot be the length of the third side of a triangle whose two sides measures 10 cm
and 5 cm?
A. 16cm B. 12cm C. 14cm D. 13cm

Answer 1

Answer:

We know that, The sum of the lengths of any two sides of a triangle is always greater than the length of the third side. The difference of the lengths of any two sides of a triangle is always smaller than the length of the third side. Therefore, 5 cm is the length of the 3rd side.

Answer 2

Answer:

(a) 16 cm

As the sum of two sides of a triangle is always greater than the third side.

Here, the sum of 10 cm and 5 cm (15 cm) is smaller than 16 cm
