Spatial Problem Solving 10, Spatial Problem Solving

1.If you apply to close the space, once the application is sent, the space flag will be cleared immediately, that is, the client does not have a space flag, no space name and dynamic updates to friends, etc., but after canceling the space, you can enter the QQ space I zone to view relevant information, which cannot be blocked for the time being;

2. If you close it, you can re-open it, but the new user questionnaire you need to fill in when you re-open it is different from that of the old user;

3. After cancellation, the relevant data of your QQ space will not be cleared, and its various plant indices and related settings will also maintain the state when you cancel the space (even if there are still a few months left in the Yellow Diamond service when you cancel the space, the nutritional index will not increase every month after cancellation; If the Yellow Diamond is still active after the space is closed, its Yellow Diamond XP will increase every day);

4. Users who re-open after closure will not be given the ** opened by new users;

5. After cancellation, the refilled information will overwrite the previous information, and the fixed module of the personal center before the space is reopened after cancellation will not change;

7. After canceling the space, the mini data card of the QQ client will not display the "QQ Space" module information;

8. Yellow diamond blocked visitors cannot prompt and cannot decorate the space, which does not affect the growth value of yellow diamond;

9. After logging out, it will not affect the access to the friend space, and the corresponding footprints will be left after the visit.

Nothing will change, it's all there.

The idea is interesting, a blind person can only locate an object in a plane, and can feel the two-dimensional space, but he can change the position at **, at this time, the two visual effects will be superimposed, and the things in the three-dimensional space can be located, so they can also feel the three-dimensional space.

In fact, people who are completely blind and completely deaf, as long as they have not been completely blind and completely deaf, then they have the same understanding of the world as ordinary people, and in the end, even if they can't see, what they feel is three-dimensional space, and as for people who are born completely blind and completely deaf, I don't know how they understand space.

1. Correct, two sets of opposite sides are parallel respectively, and it can be seen from the parallel lines in the same plane, and the quadrilateral is a plane geometry, then it can be known that there is no parallelogram.

2. Error In space geometry, two sets of figures with equal opposite sides can be formed by folding parallelograms of planes, so they are not necessarily planar figures, and they are not necessarily parallelograms.

3. If the figure is a flat figure, it must be a square, if it is not a flat figure, it is not necessarily a square, you can pick up a piece of paper and make a diamond shape with an angle of 60°, and the four sides of the diamond are equal, then fold it in half, then you can know that there must be a point that can make the other two sides think of a 60° angle, because the diamond is fixed and folded in half on every two sides, then the angle of these two braids remains the same, it is still 60°, and the other angle is also 60°, and the four sides of the diamond are equal, this figure is a spatial figure, not a plane figure, let alone a square.

The first one is correct, the definition of a parallelogram.

The second is correct.

The third is correct, isn't the corners of a quadrilateral with all four angles equal to each other ninety degrees?

What is the problem.

Space? A., founder of information processing psychology in the United StatesNewell and Simon used an important concept in the study of human problem-solving, and it is also an important aspect of human problem-solving research.

They argue that the study of human problem-solving should examine not only the actual, explicit behaviors of the subjects, but also the probable, implicit behaviors that the subjects consider in their minds. In other words, the study of human problem-solving must examine the internal space in which the problem-solving activities of the participants take place and are carried out. They call this internal space "problem space".

What is its definition? Definition: The problem solver's understanding of an objective statement of a problem, usually consisting of three components: the given conditions, the goal, and the permissible cognitive manipulation of the problem. Definition: The basic components of the understanding and formulation of the problem.

A clear definition of the three components in the problem space will help solve the problem, and a well-defined and well-defined problem is similar to a textbook question.

Hope it helps.

aca'c'To form a rectangle is in a plane, so remove aa' and cc'Two.

ABCD is in a plane, so remove the four bars AB, BC, CD, and AD, so there are still 6 bars.

6 articles. Check one by one, remove parallelism and intersection.

In other words, the study of human problem-solving in the past must examine the internal space in which the problem-solving activities of the subjects take place and are carried out. They call this internal space "problem space".

Why does the plane that is sought over the straight line l and the plane that is sought over all the points on the known straight line? Answer: If the line l is on a plane, then all the points on the line l are on the plane, which should be well understood.

Why is the "normal vector perpendicular to the normal vector of a straight line" in a plane Answer: Correct a statement: there is no "normal vector" in a straight line in space; Spatial straight lines have only normal planes.

The straight line l is on the plane, and since the normal vector of the plane is perpendicular to the plane, its normal vector must be perpendicular to l, that is, the plane is the normal plane of the straight line l. [The normal vector of the plane is perpendicular to all straight lines on the plane; l is on the plane, and therefore also perpendicular to the line] Isn't it okay to cross the line? A:

An infinite number of planes can be made through a straight line; There can be only one plane after two intersecting lines. Three or more intersecting lines may or may not be made as a plane. Your question, "Isn't it okay to cross straight lines?"

I don't know what it means?
