Question

When can we say that construction of a triangle ABC is not possible AB - BC < AC or AB – BC = AC ?​

Answer 1

Answer:

We know that, the construction of a triangle is not possible, if sum of two sides is less than or equal to the third side of the triangle. So, if AC – AB= 6.9 cm, then construction of ΔABC with given conditions is not possible. So, if AC – AB = 2.8 cm, then construction of ΔABC with given conditions is possible.

Answer 2

Answer:

✅Solution: (a) Given, BC = 6 cm and ∠B= 45° We know that, the construction of a triangle is not possible, if sum of two sides is less than or equal to the third side of the triangle. i.e., AB + BC < AC => BC < AC – AB => 6 < AC-AB So, if AC – AB= 6.9 cm, then construction of ΔABC with given conditions is not possible.✅
