Question

The tangent to the circle at p and q intersect at a point t prove that PQ and OT bisect each other at right angles

Answer 1

Step-by-step explanation:

angle opt=angle oqt=90 degree

angle t =90 degree(angle sum property)

PTQO is a square(llgm with all angles 90 degree and adjacent sides are equal)

in a square the diagonals are ⊥ bisector 

∴pq and ot are perpendiculaer bisector
