The perpendicular at a point of contact to the tangent to a circle passes through the centre
True or false
Answers
Answer:
According to me Its Definitly TRUE
Step-by-step explanation:
As Tangent of circle makes angle of 90° with Centre of the circle & from one point there is only one perpendicular possible.

True , The perpendicular at a point of contact to the tangent to a circle passes through the center
Step-by-step explanation:
The perpendicular at a point of contact to the tangent to a circle passes through the center
O is the center of the given circle.
A tangent PR has been drawn touching the circle at point P.
Draw QP ⊥ RP at point P, such that point Q lies on the circle.
∠OPR = 90°
Also, ∠QPR = 90° (Given)
∴ ∠OPR = ∠QPR
Now, above case is possible only when centre O lies on the line QP.
Hence, perpendicular at the point of contact to the tangent to a circle passes through the centre of the circle.
