The construction of a triangle ABC, given that BC = 6 cm, DB = 45° is not possible when difference of AB and AC is equal to:
A. 6.9 cm
B. 5.2 cm
C. 5.0 cm
D. 4.0 cm
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 6 cm.
Options (B), (C) and (D) satisfy the above condition.
When AB – AC = 6.9 cm, the condition doesn’t satisfy.
Ans. The construction of the given ΔABC is not possible when difference of AB and AC is equal to 6.9 cm.
