Question 203193
<font face="Garamond" size="+2">

The diagonals of a rectangle bisect each other, so the point of intersection is the midpoint of either diagonal.  Apply the midpoint formulas to the coordinates of either of the two sets of points that define the ends of either of the diagonals.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x_m\ = \frac{x_1 + x_2}{2}] and


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ y_m\ = \frac{y_1 + y_2}{2}]


Where *[tex \Large \left(x_1,y_1\right)] and *[tex \Large \left(x_2,y_2\right)] are the ends of one of the diagonals.
