TEAM PROJECT. Geometric Applications. To increase your skill in dealing with vectors, use vectors to prove the following (see the figures). (a) The diagonals of a parallelogram bisect each other. (b) The line through the midpoints of adjacent sides of a parallelogram bisects one of the diagonals in the ratio I: 3. (e) Obtain (b) from (a). (d) The three medians of a triangle (the segments from a vertex to the midpoint of the opposite side) meet at a single point, which divides the medians in the ratio 2:1. (e) The quadrilateral whose vertices are the midpoints of the sides of an arbitrary quadrilateral is a parallelogram. (n The four space diagonals of a parallelepiped meet and bisect each other. (g) The sum of the vectors drawn from the center of a regular polygon to its vertices is the zero vector. ~ w a Team Project 38(a) o~ a c C _ b ~ D~B A a Team Project 38{d) Team Project 38(e)
