Question

To divide AB in the ratio 5:1, after some stages, we draw an arc with centre at $A_6$, repeat the same with equal radius at $A_5$. Then mark the first arc ($A_6$ and $A_5$) at $C_1$ and mark the same for second arc ($A_5$ and $A_4$) at $C_2$. This is done in order to:

• A. Draw a line $A_6{B}^{\prime }$ through $C_2$.
• B. Draw an angle at $A_5$ equal to $\angle$ $A{A}_{6}B$.
• C. Make the diagram attractive .
• D. Draw $A^{\prime }{C}_2\parallel A{A}_6$

Answer 1

The correct option is B

Draw an angle at $A_5$ equal to $\angle$ $A{A}_{6}B$.

By drawing an arc with $A_6$ as centre and cutting it at $C_1$ we are measuring the angle $\angle A{A}_{6}B$. By repeating each step with $A_5$ as centre we are drawing equivalent angle at $A_5$.
