There are ways to observe objects, from different directions.

Draw a picture from multiple angles and start building it.

Plane graphics tell you, three-dimensional graphics guess.

Box of number range, count after recovery.

The size of the observation range is determined by two conditions.

Stand tall and see far; The smaller the angle, the shorter the shadow.

Points and corners are very important, good friends who restrict each other.

Extended data:

Mathematical knowledge point-observation object point

1, correctly identify the shape of the object viewed from the top, front and left.

2, there is a trick to observe the object, first count a few faces, and then look at its arrangement, pay attention when drawing graphics, only draw up and down.

3. When you observe the same object from different positions, you may see the same or different graphics.

4. Observing different objects from the same position, you may see the same or different graphics.

Only by observing from different positions can we know an object more comprehensively.
