Q.-  Prove that the tangents drawn at the ends of a diameter of a circle are parallel.
 
Sol. Given : CD and EF are the tangents at the end points A and B of the diameter AB of a circle with centre O.
To prove : CD || EF.
Circles notes 3
 
Proof : CD is the tangent to the circle at the point A.
∴ ∠BAD = 90°
EF is the tangent to the circle at the point B.
∴ ∠ABE = 90°
Thus, BAD = ABE (each equal to 90°).
But these are alternate interior angles.
 CD || EF
 
Q.- Prove that the line segment joining the point of contact of two parallel tangents to a circle is a diameter of the circle.
 
Sol. Given : CD and EF are two parallel tangents at the points A and B of a circle with centre O.
Circles notes 4
To prove : AOB is a diameter of the circle.
Construction : Join OA and OB.
Draw OG || CD
Proof : OG || CD and AO cuts them.
∴ ∠CAO + GOA = 180°
=> 90°+GOA = 180° [OA⊥CD]
=> GOA = 90°
Similarly,  GOB = 90°
∴ GOA + GOB = (90° + 90°) = 180° 
=> AOB is a straight line
Hence, AOB is a diameter of the circle with centre O.
