Question

Is it possible to construct a triangle of side 12cm, 5 cm and 4cm​

Answer 1

Answer:

No, it is not possible to construct.

Step-by-step explanation:

Because In a triangle sum of two sides will always be greater then third side.

Answer 2

Answer:

No,we can't.

Step-by-step explanation:

Let ABC be a triangle where AB=12cm Bc=5cm and  AC=4cm.

Let us add AB+BC which is 12+5=17<4.

Hence AB+BC<CA

Let us add CA+BC which is 4+5=9>12.

Hence CA+BC<BA

Hence, we cannot construct triangle where  AB=12cm Bc=5cm and  AC=4cm.
