Question

The construction of a triangle ABC in which AB = 4 cm, ∠A = ${60}^{\circ }$ is not possible when the difference of BC and AC is equal to

• A. 2.5 cm
• B. 3 cm
• C. 3.5 cm
• D. 4.5 cm

Answer 1

The correct option is D 4.5 cm

Explanation: Among the options given, 4.5 > 4,
Since the difference of any two sides of a triangle cannot be greater than the third side. So the difference of BC and AC is not equal to 4.5 cm.
