D raw any  angle  with vertex  o.  take a point  a on  one  of  its arms  and B  on. another such  that  OA=OB.  Draw  the  perpendicular  bisectors of  OA and  OB.   Let  them  meet  atP.  Is   PA=PB?

Let O be any point and we draw any angle ∠AOB with vertex at O with any point A on one of its arms and B on other arm.

Now draw the perpendicular bisectors of OA and OB as

By using Ruler and compass, we draw perpendicular bisector of line segment OA and similarly draw the perpendicular bisector of line segment OB.

Suppose, they meet at the point P.

Using scale, we measure and see that AP = BP
