A, parallelogram mind map drawing:

Mind mapping is a graphical expression tool, which is used to show and organize the thinking process. To draw the mind map of parallelogram, we must first make clear the definition and characteristics of parallelogram. A parallelogram is a quadrilateral with two pairs of parallel sides.

Choose a center point on the paper, mark it as A, and draw a line segment from point A to represent one side of the parallelogram. You can choose any length, mark one end of the line segment as B. Starting from point B, draw a line segment parallel to AB, representing the other side of the parallelogram, and mark one end of the line segment as C.

Starting from point C, draw a line segment parallel to AB and BC to represent the other side of the parallelogram, mark one end of the line segment as D, start from point D, draw a line parallel to AD to represent the last side of the parallelogram, and then connect to point A to form a closed figure.

Second, the trapezoidal mind map drawing:

A trapezoid is a quadrilateral with two parallel sides and the other two are not parallel. Select a center point on the paper and mark it as a. Draw a line segment from point A to represent one side of the trapezoid. You can choose any length, mark one end of the line segment as B. Starting from point B, draw a line segment parallel to AB, representing the other side of the trapezoid, and mark one end of the line segment as C.

Starting from point C, draw a line segment that is not parallel to AB and BC, representing the hypotenuse of the trapezoid. This line segment can be of any length, but it cannot be parallel to AB and BC, nor can it coincide with them. One end of the line segment is marked as D. Starting from point D, draw a line segment parallel to AD, representing the last side of the trapezoid, and connect it back to point A to form a closed figure.

Third, the introduction of mind mapping:

Mind mapping, also known as mind mapping, is an effective graphic thinking tool to express divergent thinking. It is simple, effective and efficient, and it is a practical thinking tool. Mind mapping uses the skills of paying equal attention to graphics and texts, showing the relationship between topics at all levels with hierarchical diagrams of mutual subordination and correlation, and establishing memory links between topic keywords, images and colors.

Mind mapping makes full use of the functions of the left and right brain and the laws of memory, reading and thinking to help people develop in a balanced way between science and art logic and imagination, thus opening up the infinite potential of the human brain. Therefore, mind mapping has a powerful function of human thinking.
