Question

Which of the following geometrical figure would help you go ahead and draw angles without using protractors?

• A. Line
• B. Perpenidcular bisector
• C. Arcs (part of a circle)
• D. None of these

Answer 1

The correct option is C

Arcs (part of a circle)

Since we need points which are at an equal distance from a given point, our first logical choice of a geometrical figure would be – Circles.
In a circle, all the points on the circumference are at a constant distance from a point called the centre.
In the above problem, from P, if we draw an arc which intersects the rays PA and PB as shown in the figure.
So, a part of a circle, i.e. an arc would also be at a constant distance from a given point.
