Question

Prove that the tangents drawn at the ends of a diameter of a circle are parallel.​

Answer 1

Fertilization can be defined as the union of two haploid gametes, the spermatozoa and the oocyte, hereto referred to as egg, to restore the diploid state, form a zygote through the process of egg activation

Answer 2

Answer:

Here's your answer

Step-by-step explanation:

First, draw a circle and connect two points A and B such that AB becomes the diameter of the circle. Now, draw two tangents PQ and RS at points A and B respectively.

• Now, both radii i.e. AO and OB are perpendicular to the tangents.

• So, OB is perpendicular to RS and OA perpendicular to PQ

• So, ∠OAP = ∠OAQ = ∠OBR = ∠OBS = 90°

• From the above figure, angles OBR and OAQ are alternate interior angles.

• Also, ∠OBR = ∠OAQ and ∠OBS = ∠OAP (Since they are also alternate interior angles)

So, it can be said that line PQ and the line RS will be parallel to each other.

Hence Proved
