The proof for Thales theorem

Answer 1

Image result for The proof for Thales theorem

Thales's theorem is a special case of the following theorem: Given three points A, B and C on a circle with center O, the angle ∠AOC is twice as large as the angle ∠ABC. See inscribed angle, the proof of this theorem is quite similar to the proof of Thales's theorem given above.

when a person askes a question there will be two answers given by the other users u can thank them if u feel anyone's answer as inappropriate u can report that and give the reason then moderators will delete that answer if u feel someone's answer as really good there will be option beside the thanks then its the mark for brainliest answer u can mark that

PLZ MARK MY ANSWER AS BRAINLIEST

Answer 2

hi  Arundhat...... i hope this will help you

Thales' Theorem

In geometry, Thales' theorem states that if A, B and C are points on a circle where the line AC is a diameter of the circle, then the angle ∠ABC is a right angle. fig 1

Apparently, another theorem also known as Thale’s theorem talks about triangular geometry where any line passing through a triangle and parallel to one side, Divides the other two sides in equal ratios

If a lind drawn parallel to a side of a triangle than it divids other two to sides propotionaly

proof done in paper
