Question

Construct a rhombus $ABCD,$ such that :
Base $AB=3.8cm$ and $\angle DAB={30}^o$

Answer 1

$\Rightarrow$ Draw a line segment $AB=3.8cm$

$\Rightarrow$ Take $A$ as center and draw an angle of ${30}^o.$

$\Rightarrow$ Cut off $AD=3.8cm$

$\Rightarrow$ Take $B$ as center with radius $3.8cm$ and draw an arc.

$\Rightarrow$ Take $D$ as center with radius $3.8cm$ and draw an arc, which meets previous arc at point $C.$

$\Rightarrow$ Join $BC$ and $CD.$

$\therefore$ $ABCD$ is required rhombus.
