3.  Circle is a collection of all points which are
equidistant from a point.

4.  Chord is a line joining any two points on the
boundary of a circle
l
Here ‘l’ is the length of the chord

5.  Radius is a line joining the center and any
point on the boundary of the circle
Here ‘ r ’ is the radius
r

6. Here ‘ d ‘ is the perpendicular distance from the centre to the
chord
d

7. d
r
l
Length of the chord can be found out by using Pythagoras Theorem

8.  Length of the chord(l) =2 √(r²-d²)
