The Triangle Midsegment Theorem states “In a triangle, the segment joining the midpoints of any two sides will be parallel to the third side and half its length.”
Thus, segment BC is half of the distance between Miami and San Juan.
Given that the distance between Miami and San Juan is 1070 miles, thus the distance between points B and C is given by
[tex]|BC|= \frac{1070}{2} =535\ miles[/tex]
