Answer to Question #20714 in Geometry for Marc A Resasco
In parallelogram ABCD, the coordinates of A are (7,3) and of C are (5, -1). What are the coordinates of the intersecton of the diagnals.
The coordinates of the intersection of the diagonals (6.5 , 1) the& coordinates of the intersection of the diagonals is in the middle of& the line, which concatenates point A and C, its easy to calculate the middle of AC . Here we use the theorem of the middle line in triangle.
