Parallelogram Midpoints Demonstration

This example demonstrates the property of a parallelogram where the line segment connecting the midpoints of opposite sides is parallel and equal to half the length of those sides. It involves core mathematical concepts such as parallelograms, midpoints, vectors, and coordinate geometry. The construction uses commands like Line, Intersect, Polygon, Midpoint, and Segment. It is suitable for high school students learning about important geometric properties of parallelograms and for geometry construction lessons.
