Basic knowledge of triangle The school has a piece of green space. First, I plan to start from the position indicated by point d (BD: DC = 2:1). I hope the green space on both sides of the small ditch is equal. Now D is not the midpoint of BC. How can I divide the green space into two equal blocks and pass through point d?

The intersection point of the middle lines on any two sides of the triangle is the center of gravity of the triangle. Any straight line passing through the center of gravity divides the triangle into two equal parts, so the green space can be divided into two equal parts by connecting the center of gravity with point D
