If the points A(1, 2), B(4, 3), C(1, 0) and D(p, -1) are the vertices of a parallelogram then, find the value of p.
The points A(1, 2), B(4, 3), C(1, 0) and D(-2, -1) are the vertices of a parallelogram. “The midpoints of AC and BD are the same.”
Show that A(1, 2), B(4, 3), C(6, 6) and D(3, 5) are the vertices parallelogram. Show that ABCD is not a rectangle.
