Question

prove that the tangents to a circle at the end points of a diameter are parallel​

Answer 1

lets take a circle with centre o and then diameter ab

when we draw them tangets at a and b we get 2 tangets and the angle formed is 90 degrees

but if we observe the diameter acts as a transversal and then they have alternate interior angles are same

which proves that those 2 lines are parallel

therefore,

that the tangents to a circle at the end points of a diameter are parallel

plz mark as brainliast

Answer 2

Step-by-step explanation:

1. Draw the diagram as given in the question
2. Now from the centre draw lines to touch the tangents
3. So both of them will have 90° angle.
4. So u will also see that transversal angles are also equal and are 90°
5. So as the transversal angles are equal
6. Both the lines are Parallel
