Using the Midpoint Theorem, what do we know about the third side of a triangle in relation to the line segment that joins the other two sides at the midpoints?

• The third side is double the length of the line segment connecting at the midpoints of the other two sides

• The third side is one-half the length of the line segment connecting at the midpoints of the other two sides.

• The third side is equal to the length of the line segment connecting at the midpoints of the other two sides.

• The third side is triple the length of the line segment connecting at the midpoints of the other two sides.
