Prove that the tangents drawn at the end points of a chord of a circle make equal angles with the chord
Circles (10)Prove that the tangents drawn at the end points of a chord of a circle make equal angles with the chord.
Answer
Case I:
Since PA = PB
Therefore in ΔPAB
∠PAB= ∠PBA
Case II:
If the tangents at A and B are parallel then each angle between chord and tangent = 90°
