WebBasic Proportionality Theorem . A prominent Greek mathematician, Thales, developed the fundamental proportionality theorem, which is also known as a Thales theorem. In his view, the ratio of each two matching sides is always the same for any two equiangular triangles. He gave a theorem of basic proportionality based on this idea (BPT). WebThere are many ways to prove this theorem. One of the most classic proofs is as follows: We know AO=BO=CO AO = BO = C O as all of them are the radii of the circle. Hence, \angle OAB=\angle OBA ∠OAB = ∠OBA and \angle …

WebJan 30, 2024 · Proof of Basic Proportionality Theorem Let us look at the proof of the Basic proportionality theorem: Statement: In a triangle, if the line drawn parallel to one side of a triangle intersects the other sides at the two points, and then it divides the other two sides in an equal ratio. Given: Consider the triangle \ (ABC\) shown in the figure below. 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. fwd50 2020

WebA few important theorems are: Theorem 1: Equal chords of a circle subtend equal angles, at the centre of the circle. Converse of Theorem 1: If two angles subtended at the centre, by two chords are equal, then the chords are of equal length. Theorem 2: The perpendicular to a chord, bisects the chord if drawn from the centre of the circle.
