Draw one line segment and two line segments in each triangle to make it three and six triangles It refers to two triangles, one is to draw one, to become three triangles, the other is to draw two, to become six triangles, how to solve it? Ha ha, yes, this is the topic of summer homework in grade 4 of primary school.
