The line drawn from the midpoint of one side of a triangle, parallel to another side, bisects the third side. This is a consequence of which theorem?
Explanation
Explanation
The Basic Proportionality Theorem (Thales' theorem) states that a line parallel to one side of a triangle divides the other two sides proportionally; applied with the midpoint (ratio 1:1), it shows the line bisects the third side too.
