The vertices of the rectangle ABCD have coordinates (-1, -3) (5, -3) (5,2) (-1,2), respectively. Find the abscissa

The vertices of the rectangle ABCD have coordinates (-1, -3) (5, -3) (5,2) (-1,2), respectively. Find the abscissa of the intersection point of the diagonals of this rectangle.

To solve the problem, you need to find the midpoint of any diagonal.

Let it be BD (5, -3) (-1,2).

The middle of the side is found as follows: (5 + (1) / 2, – 3 + 2 \\ 2).

Then it turns out: the coordinates of the midpoint of the diagonal (2, -0.5).

We need the abscissa, that is, the x coordinate, and this is 2.

Answer: 2.
