geometry - Converse of Thales' theorem

This is the converse of Thales' theorem I know that there are different proofs of this, but I'm trying to do it according to the hint of the book, which is the following: Hint: Chose a point $C'$ on $\overrightarrow MC $ so that $MC' = AM$. By Theorem 8.3.1 Thales' theorem, $\angle AC'B$ is a right angle. Use the Exterior Angle Theorem in a proof by contradiction to show that $C = C'$.

Basic Proportionality Theorem or Thales.

Basic Proportionality Theorem or Thales Theorem. Statement: If a line is drawn parallel to one side of a triangle intersecting the other two sides, then it divides the two sides in the same ratio. Given: A triangle ABC in which DE BC, and intersects AB in D and AC in E. Basic Proportionality Theorem & Similar Triangles Basic Proportionality theorem was introduced by a famous Greek Mathematician, Thales, hence it is also called Thales Theorem. According to him, for any two equiangular triangles, the ratio of any two corresponding sides is always the same.

Thales' 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. History. Thales was not the first to discover this theorem since the Egyptians and Babylonians must have known of this empirically. Thales' Theorem. A theorem that is credited to Thales after Thales of Miletus, c. 620 - c. 546 BC is the subject of Euclid's Elements VI.2: If a straight line is drawn parallel to one of the sides of a triangle, then it cuts the other sides of the triangle, or these produced, proportionally; and, if the sides of the triangle, or the sides.

25.11.2013 · If angle ACB is a right angle, then C is on the circle that has AB as a diameter. Hint: The three points A, B, and C determine a unique circle by what theorem?. Apply the Inscribed angle theorem to complete the proof. Please please help. Understand the Converse. Break students into small groups and ask each group to research the converse of Thales' theorem. They should read about what the converse.

Converse. The converse of Thales' theorem is also valid; it states that a right triangle's hypotenuse is a diameter of its circumcircle. Combining Thales' theorem with its converse we get that: The center of a triangle's circumcircle lies on one of the triangle's sides if and only if the triangle is a right triangle.

A Proof for the Converse of the Pythagorean Theorem. Converse of the Pythagorean Theorem: If the square of the length of the longest side of a triangle is equal to the sum of the squares of the lengths of the other two sides, then the triangle is a right triangle. Thales of Miletus 624 - 546 BC Thales of Miletus was one of the seven sages of Greece and considered by Aristotle to be the first philosopher in the Greek tradition. The twentieth century philosopher Bertrand Russell goes further and says that Western philosophy begins with Thales. As far as we are concerned, Thales was.

Converse of Basic Proportionality Theorem. Converse of Basic Proportionality Theorem: If a line divides any two sides of a triangle in the same ratio, then the line must be parallel to the third side. Given: A Δ ABC and a line intersecting AB in D and AC in E, such that AD / DB = AE / EC. Divide both sides by 2 and we have returned to Thales’ Theorem, because α β = 90. One Practical Application of Thales’ Theorem. A simple but practical application of Thales’ Theorem is to find the center of a circle, assuming you can draw a couple of right-angle triangles over it.
