Obviously, the figure is divided into two figures by a straight line, and the size of the two figures is two and a half squares.

First: There are three vertical lines in this picture. We label them as A, B and C respectively, and connect the vertex of A and the penultimate point of B from top to bottom to get two graphs with equal areas.

Second, this connection can be divided into two graphs with the same area with the second point from the top of C as the point and the second point from the bottom of B as the point.
