Question

Which of the following could represent length (in cm) of sides of a triangle?

• A. 1 , 2, 3
• B. 3, 4, 5
• C. 4, 5, 10
• D. 2, 4, 6

Answer 1

The correct option is B 3, 4, 5

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> For a geometrical figure to be a triangle, the sum of lengths of any two sides must be greater than the third side. Otherwise, a triangle cannot be formed.

Here, other than sides (in cm) 3, 4, and 5, none of the other sets satisfy the above condition.
