Question

state basic proportionality theorem
​

Answer 1

Answer:

Basic Proportionality Theorem states that 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. In this video, we will discuss about the concept of basic proportionality theorem and similar triangles.

Answer 2

Answer:

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. Based on this concept, he gave theorem of basic proportionality (BPT). This concept has been introduced in similar triangles.  If two triangles are similar to each other then,

i) Corresponding angles of both the triangles are equal

ii) Corresponding sides of both the triangles are in proportion to each other
