To prove:
N is the midpoint of
Given:
We need to prove, “If a line is parallel to one side of a triangle and passes through the midpoint of a second side, then it will pass through the midpoint of the third side”.
In
Property used:
MeansExtremes Property:
In a proportion, the product of the means equals the product of the extremes; that is, if
If a line is parallel to one side of a triangle and intersects other two sides, then it divides these sides proportionally.
Proof:
Consider
