Question

9. In which of the following cases is the construction of a triangle is possible:
(a) AB=3 cm, BC=4cm, CA-Icm.
(b)AB=5 cm, BC=7cm, CA=8cm.
(c) AB=9 cm, BC=4cm, CA=3cm.
(d) AB=10 cm, BC=7cm, CA=8cm.
​

Answer 1

A triangle can be constructed only when sum of two smaller sides of triangle is greater than third side.

Therefore, this is possible

(b)AB=5 cm, BC=7cm, CA=8cm.

(d) AB=10 cm, BC=7cm, CA=8cm.

Answer 2

Make all traingle

Add all traingle

If the angle of a traingle is exact 180°

Neither less or more

Than the construction is possible
