3 days ago 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. See more
1 week ago WEB Jun 6, 2018 · Question of Class 10-Basic Proportionality Theorem (Thales Theorem) : F or any two equiangular triangles, the ratio of any two corresponding sides of the given triangles is always the same. Based on this concept, the basic proportionality theorem (BPT) was proposed. If a line is drawn parallel to one.

1 week ago WEB Mar 27, 2021 · In today's lesson, we will prove Thales' Theorem - the inscribed angle that subtends the diameter of a circle is always a right angle, using the sum of angles in a triangle. Thales of Miletus was a Greek mathematician who's work predates that of Euclid and Pythagoras. There are a number of theorems associated with his name.
