Question

For construction of a quadrilateral $ABCD$, where$AB=4.2$ cm, $BC=3.8$cm, $CD=4.9$cm, $AD=5.4cm$ and $\angle B=72$, its steps for construction is given in jumbled form. Identify the third step from the following
1) From $B$, set off $BC=3.8$ cm.
2) Draw $AB=4.2$ cm and : Make $\angle ABX=72$.
3) With $A$ as center and radius equal to $5.4$ cm draw an arc.
4) With $C$ as center and radius equal to $4.9$ cm, draw another arc, cutting the previous arc at $D$. Join $AD$ and $CD$

• A. $3$
• B. $1$
• C. $4$
• D. $2$

Answer 1

The correct option is A $3$

$\Rightarrow$ We have to construct quadrilateral ABCD for that we have given steps.

$\Rightarrow$ First is to draw $AB=4.2cm$ and make $\angle ABC={72}^{\circ }$

$\Rightarrow$ Second is from B, set off $BC=3.8cm$

$\Rightarrow$ $3^{rd}$ step will be : -

$\Rightarrow$ With A as center and radius equal to $5.4cm$ draw an arc.
