Question

plzz explain basic proportionality theorem plzz

Answer 1

Answer:

basic proportionality theorem states that if a line is drawn parallel to one side of a triangle to intersect other 2 sides in distinct points , the 2 sides are divided in the same ratio

EXAMPLE (see given attachment)

      EF// BC       EF meets AB at E and meets AC at F

       

        here,

                  AB/EB = AF/FC

$<b> Basic Proportionality Theorem was first stated by Thales, a Greek mathematician. Hence it is also known as Thales Theorem. Thales first initiated and formulated the Theoretical Study of Geometry to make astronomy a more exact science. What is this theorem that Thales found important for his study of astronomy? Let us find it out.$

$<b> Basic Proportionality Theorem (can be abbreviated as BPT) states that, if a line is parallel to a side of a triangle which intersects the other sides into two distinct points, then the line divides those sides in proportion.$
