Question

AB is a diameter of a circle L1 AND L2 are tangents to a circle drawn at A and B respectively, then​

Answer 1

Answer:

Step-by-step explanation:Correct option is A)

Here AB is a diameter of the circle with centre O, two tangents PQ and RS drawn at points A and B respectively.

Radius will be perpendicular to these tangents.

Thus, OA ⊥ RS and OB ⊥ PQ

∠OAR=∠OBP=∠OBQ=90  

0

 

Therefore,

∠OAR=∠OBQ (Alternate interior angles)

∠OAS=∠OBP (Alternate interior angles)

Since alternate interior angles are equal, lines PQ and RS will be parallel.
