Question

If 'a', 'b' and 'c' are the three sides of a triangle, then choose the incorrect option out of the following options to construct a unique triangle.

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

Answer 1

The correct option is C a + c < b

To construct a unique triangle with the three sides given, sum of any two sides must be greater than the third side.

Hence,
Options a and d are correct, and
Option b is same as the option a, so it is also correct.

Only option c is incorrect where sum of two sides 'a' and 'c' is less than the third side 'b'.
