Basic proportionality theoram :-
If a line is drawn parallel to one side of a triangle intersecting two sides, then it divide the two sides in the same ratio.
In ∆abc, if DE||BC and intersects AB in D and AC in E then,
AD AE
=
DB BC
....................,.....,........,...,...........,....,............. .........., .........
proof the Thales Theorem..
of a line is drawn parallel to one side of a triangle and it in intersects the other two sides at two distinct points then it divides the two sides in the same ratio.
