Q3 of 22 Page 109

The construction of a triangle ABC, given that BC = 3 cm, DC = 60° is possible when difference of AB and AC is equal to:

We know that the difference of any two sides of a triangle is less than the third side.


So, (AB – AC) must be less than 3 cm.


Options (A), (B) and (C) do not satisfy the above condition.


When AB – AC = 2.8 cm, the condition satisfies.


Ans. The construction of the given ΔABC is possible when difference of AB and AC is equal to 2.8 cm.
