Final answer:
The midsegment of a trapezoid is parallel to both bases.
Step-by-step explanation:
The statement that is correct about the midsegment of a trapezoid is C. The midsegment is parallel to both bases.
A midsegment of a trapezoid is a line segment that connects the midpoints of the legs of the trapezoid. In this case, RS is the midsegment of trapezoid KLMN.
Since RS connects the midpoints of KL and MN, it is parallel to both bases KL and MN. This can be proved using coordinate geometry by assigning coordinates to the vertices of the trapezoid and showing that the slopes of RS and the bases are equal.
