The line segment VY connects the midpoints of two sides of triangle WZX. This makes VY a midsegment of the triangle. The triangle midsegment theorem states that the midsegment is parallel to the third side of the triangle and half as long as that third side.
Step 2: Apply the Theorem
In this case, the midsegment VY is parallel to WX and its length is half the length of WX.
