प्रश्न
The tangents drawn at the extremities of the diameter of a circle are ______.
पर्याय
perpendicular
parallel
equal
intersecting
none of these
उत्तर
The tangents drawn at the extremities of the diameter of a circle are parallel.
Explanation:
Since OP ⊥ AB and OQ ⊥ CD
∴ Z1 = 90° and Z2 = 90°
⇒ ∠1 = Z2, which are alternate angles.
∴ AB || CD
