Solution

The correct option is A True
Given :
A chord PQ of a circle C(O,r) and perpendicular OL to the chord PQ.
To Prove :
LP=LQ
Construction :
Join OP and OQ.
Proof :
In triangles PLO and QLO,
OP=OQ=r
OL=OL
OLP=OLQ
So, by RHS-criterion of congruence,
PLOQLO
PL=LQ
Hence, proved.
Thus, the given statement is true.
