Question

Explain how to construct an equilateral $△ABC$ of side $5cm$, with the help of compass and ruler.

Answer 1

We know that,

Equilateral triangle means all the sides of a triangle are equal.

$\Delta ABC$ has to be constructed with $AB=BC=CA=5cm$.

Then,

Draw a line segment $BC$ of $5cm$.

Taking point $B$ as center, draw an arc of $5cm$ as radius.

Both arc will intersect at point $A$.

Join $A$ and $B$; $A$ and $C$.

$ABC$ is the required equilateral triangle.
