Q. 23.8( 6 Votes )

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

Answer :

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.
