Question

what is the construction to find the centre of the circle plz help

Answer 1

first u need to draw two equal chords of circle then
u have to draw the perpendicular bisector of both the chords (by opening the compass mor than half of th chords and makin arcs from both of the ends points of chord and also intersecting the arcs up and down and then joining them)
then u need to extend both the perpendicular bisector inside the circle
the point where the perpendicular bisectors will intersect will be the center
hope it helps....

Answer 2

Step1:draw any two tangents on the circle.
Step 2:draw perpendiculars at the point of contact of the tangents and the circle.

The point where the perpendiculars of the two tangents meet is the center of the circle.
