Use two circles, two triangles and a rectangle to form a figure
Please draw a straight line on the graph so that the figure below is a triangle and a trapezoid
The drawing is as follows:
Add a straight line and divide the figure below into 2 triangles
Here is a rectangular piece of paper. Please draw a line and divide it into two parts. Then cut it along this line. These two parts can be cut into triangles,
Connect the two opposite points of a rectangular piece of paper. Cut along this line. The two parts can be cut into triangles
In the triangle, draw a line into two triangles, then draw n lines how many triangles
Draw a line from the same fixed point to three triangles
Two lines make six triangles
Σ=(n+2)×(n+1)÷2
How to draw a line in a trapezoid to make it a triangle and a Pentagon
Can I send a diagram
=&Such a simple question
Add a line to a Pentagon to make it two triangles
Draw a thick line
A quadrilateral, how to draw a line, can make it into three triangles?
Define a quadrilateral as ABCD
Draw a line from a to a point E on CD on the opposite side of AB (point E does not coincide with C and D), and fold back to point B through point E
This line is a broken line AEB
