Description:
When a line or plane is parallel to the projector, its projection reflects real or real form, which shows the reality of the projection. (5 points)
Correct the error
Answer: correct
Their thinking:
The positive projection is equal to the length of the horizontal projection. The positive projection is the same height as the lateral projection. The horizontal projection is equal to the width of the lateral projection. That is, "long pair of positive, high level, width equal". (5 points)
Correct the error
Answer: correct
Their thinking:
As you can see from the diagram below, line AB is parallel to CD. (5 points)
Correct the error
Answer: correct

Correct the error
wrong
Their thinking:
We know that the point A is (10, 15, 8), and the point B is (15, 5, 12), and A is at the top of B. (5 points)
Correct the error
wrong
Their thinking:
According to the relative position of the line AB and the projection surface, the AB is the positive parallel line. (5 points)
Correct the error
Answer: correct
Their thinking:
As is shown in the figure, it is correct to judge the
