Question

why can't you construct ∆ABC with AB=7cm BC=5cm CA= 2cm? Explain​

Answer 1

Answer: We cannot construct it.

Step-by-step explanation:

By triangle inequality property, two sides should sum up to more than the third side and cannot be equal or lesser.

a+b>c

Here, in these dimensions, the sides of BC and CA sum up to 7, meaning it is equal. But it defies the triangle inequality property, so it is not a triangle. Therefore, it cannot be constructed.
