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 first step from the following:
1) From $B$, set off $BC=3.8$ cm.
2) Draw $AB=4.2$ cm and Make $\angle ABX={72}^{\circ }$.
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. $2$
• B. $3$
• C. $4$
• D. $1$

Answer 1

Answer: (A)

$2$

$\Rightarrow$ We have to construct quadrilateral ABCD, for that we have given steps for construction in jumble form.

$\Rightarrow$ To construct quadrilateral ABCD $1^{st}$ step will be :-

$\Rightarrow$ Draw $AB=4.2cm$ and make $\angle ABX={72}^{\circ }$
