Question

Show that tangent lines at the end points of a diameter of a circle are parallel.

Answer 1

Answer:

Step-by-step explaHere 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 = ∠OAS = ∠OBP = ∠OBQ = 90º

Therefore,

∠OAR = ∠OBQ (Alternate interior angles)

∠OAS = ∠OBP (Alternate interior angles)

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

Answer 2

first of fall you draw a circle and and down part of the circle can draw a ling and pass on the tangent
