Question

6. If two sides of a triangle are 5cm &1.5 cm,
the length of its third side cannot be......​

Answer 1

Answer:

(d) Given, the length of two sides of a triangle are 5 cm and 1.5 cm, respectively.

Let sides AB = 5 cm and CA = 1.5 cm

We know that, a closed figure formed by three intersecting lines (or sides) is called a triangle, if difference of two sides < third side and sum of two sides > third side

∴ 5-1.5 < BC and 5+1.5 > BC

⇒ 3.5 < BC and 6.5 > BC

Here, we see that options (a), (b) and (c) satisfy the above inequality but option (d) does not satisfy the above inequality.

Answer 2

• show the triangle is three sides one side is a one side is b and one is C the a n c should be equal and the biwi not equal with the two sides so the other side is 5cm 20 1.5 CM CD is 5 cm
