Next to the Zhongshan Park under construction, there is a triangular open space with the shape shown in Figure 2. You can divide △ ABC into four triangles with equal area to plant four different kinds of flowers and plants. Please help to draw the planning scheme (at least two kinds) What about that triangle? No rules

At least two options?
O
So,
In the first scheme, the midpoint of each side is taken to connect four triangles of equal area
In the second scheme, one side is divided into four equal parts and connected from the vertex to form four triangles of equal area



It is required to draw a line segment through a vertex of a triangle and divide the triangle into two parts equally. How to draw?


The middle line of triangle can divide the triangle into two parts with equal area;
So make a middle line through the vertex!



A triangle is divided into two triangles by drawing a line segment through one of its vertices. The sum of the inner angles of one of the triangles is ()
A. 180 ° B. 90 ° C. uncertainty


Because the sum of the internal angles of a triangle is 180 degrees, and it has nothing to do with the shape of the triangle. No matter whether the triangle is large or small, its sum of internal angles is fixed, and it is 180 degrees
