Question

Which among the following is not the correct step while replicating an angle using compass, ruler and pencil?

• A. Draw a line with the straight edge and mark a point on it
• B. Draw an arc of any radius, centered at point $O$ of angle $AOB$
• C. Using the same radius, draw an arc on the new ray
• D. Draw an arc of unit radius, centered at $B$ of angle $AOB$
• E. Measure the distance between the points where the arc intersects the arms of angle $AOB$ with the compass

Answer 1

The correct option is D Draw an arc of unit radius, centered at $B$ of angle $AOB$

The steps involved while replicating an angle are as follows:

• Draw a line with the straight edge and mark a point on it
• Draw an arc of any radius, centered at point $O$ of angle $AOB$
• Using the same radius, draw an arc on the new ray
• Measure the distance between the points where the arc intersects the arms of angle $AOB$ with the compass
• With the same length, draw an arc, centered at the intersection point of the earlier arc and ray
• Draw a line segment from $O^{\prime }$ to the intersection point of the two arcs
