Question

Construct an equilateral triangle whose sides are of length $5.5$ cm.

Answer 1

Steps of construction :
1. Draw $BC=5.5$ cm.
2. With $B$ as centre, draw an arc of radius $5.5$ cm.
3. With $C$ as centre, draw another arc of radius $5.5$ cm, which cuts the former arc at $A$.
4. Join $AB$ and $AC$.
Hence, $\Delta ABC$ is required equilateral triangle.
