Question

If a, b and c are the sides of a triangle, then which of the following is true?

• A.
  $a-b>c$
• B.
  $a-c>b$
• C.
  $b-c=a$
• D.
  $a-b<c$

Answer 1

The correct option is D

$a-b<c$
The difference between any two sides of a triangle is less than the third side. So, we have,
$a-b<cb-c<aa-c<b$

Thus, the correct answer is option (d).
