Question
Construct a rhombus whose side $AB = 5\ cm$ and diagonal $AC = 6\ cm$. $ME$ asure $DB$ and $AD.$
✓
Answer
In rhombus all sides are equal.
$1)$ Draw $AC = 6\ cm.$
$2)$ With $A$ as centre and radius $5\ cm$, draw two arcs one above $ac$ and the other below $AC.$
$3)$ With $C$ as centre and radius $5\ cm$ draw two acrs one above $AC$ and the other below $AC$ intersecting the arcs of Steps $2$ in $B$ and $D$ respectively.
$4)$ Join $AB, BC, CD$ and $AD.$
$5) \text{ABCD}$ is the required rhombus.
$6)$ On measuring, $AD = 5\ cm$ and $DB = 8\ cm.$
