The midpoint theorem states that there is a parallel to the line that joins two sides of a triangle on the third side.
In a given triangle, if there are different sides to a triangle, then the midpoint is parallel to the third side from two sides of the same triangle.
For example:
If E and D are the midpoints of the sides AC and AB.
Then the line DE is said to be parallel to the side BC because the side DE is half of the side BC; i.e. DE = (1/2 * BC).
Hence, we can see that your question is incomplete, so a general overview is given to you about the midpoint theorem and how it is used.
