Question

The $4^{th}$ step is:

• A. Draw an arc of length $CD$ on the line $\parallel AB$. Join $C-D$
• B. Draw a line from $C\parallel AB$
• C. Draw an arc of length $BC$ from $B$ and of length $AC$ from $A$ and mark the intersection point as $C$. Join $B-C$ and $A-C$
• D. Draw base $AB$

Answer 1

The correct option is A Draw an arc of length $CD$ on the line $\parallel AB$. Join $C-D$

To construct a trapezium, we need to draw base first

So, first step will be draw base $AB$ i.e. $\left(ii\right)$.

Then $\left(iii\right)$ i.e Draw an arc of length $BC$ from $B$ and of length $AC$ from $A$. Then mark the point of intersection as $C$ and join $B-C$ and $A-C$.

After drawing $B-C$ and $A-C$, we can draw a line from $C$ parallel to $AB$.

So, next will be $\left(ii\right)$ i.e. draw a line from $C\parallel AB$

And then draw an arc of length $CD$ on the line $\parallel AB$ .

Hence, $\left(i\right)$ will be the $4^{th}$ step.
