Move two matches to change the direction of the room

Answer: Move the two matches in Figure 1 to the position in Figure 2.

Comments: This question examines the relevant knowledge of three-dimensional graphics, examines students' spatial imagination ability, and hands-on ability.

Details:

Spatial imagination is the abstract thinking in which people observe, analyze, and recognize the spatial form (spatial geometry) of objective things.

Cultivating students' spatial imagination is one of the main tasks of middle school mathematics teaching, but it is also one of the difficulties.

In teaching, if the term spatial imagination is only mentioned too much, the rational analysis is not enough, and the law of its cultivation cannot be grasped, it may lead to the result that the spatial imagination of a small number of perceptive students has been improved, while the majority of students have little benefit, and even regard the "Solid Geometry".

Learning is daunting.

Turn the diagonal stick in the middle into a vertical one, and connect it with the vertical one below, and you're done.

Mathematics is a general means for humans to strictly describe the abstract structure and pattern of things, and can be applied to any problem in the real world, and all mathematical objects are inherently artificially defined. In this sense, mathematics belongs to the formal sciences, not the natural sciences. Different mathematicians and philosophers have a range of opinions on the exact scope and definition of mathematics.

Square Decision Theorem.

1: A diamond with an equal diagonal is a square.

2: A diamond with a right angle is a square.

3: Rectangles with diagonal perpendicular to each other are squares.

4: A set of rectangles with equal adjacent sides is a square.

5: A set of parallelograms with equal adjacent sides and one corner at right angles is a square.

6: A parallelogram with diagonal lines perpendicular to each other and equal to each other is a square.

7: Quadrilaterals with equal diagonals and bisected perpendicular to each other are squares.

8: A group of quadrilaterals with equal adjacent sides and three corners that are right angles is a square.

9: A quadrilateral that is both a diamond and a rectangle is a square.

Summary. Move 3 matchsticks to make the house on the left look like a right+.

Dear, just move the middle two to the left.

The lower part of the house can be seen as two squares, which will not affect the direction of the small house, so consider analyzing the figure of the upper part of the house;

The upper part is a parallelogram and a triangle, and the length of each side of the two figures is the length of a match.

It took a while to make an animation, and it should be clear at a glance.

If moving matches does not specifically refer to the flat head jujube moving)

The lower part of the house can be seen as two squares, which will not affect the direction of the small house, so consider analyzing the figure of the upper part of the house;

The upper part is a parallelogram and a triangle, and the length of each side of the two figures is the length of a match;

Move both to the position shown in purple.

I don't know if that's what you mean, I hope it helps

Please give a picture, otherwise I don't know how to do it.
