What the hell is that thing 20, what is the shape of that thing?

Everyone is different and it's okay as long as it doesn't affect your sex life.

Please use a different pose.

Hehe, it should be normal, take a look at it, it's okay if you can; Phew.

If it's hard, it's fine

Definitions of Terms一、strange [ qí guài ]

1. It is very different from the general situation.

2. Unexpected and incomprehensible.

Lao She's "Not a Problem": "That woman is not very good-looking. But the eyes were so strange that it was impossible not to pay attention to her. ”

2. Peculiar [ qí tè ].

Strange and special; It's very different from the usual.

Guo Moruo's "Hongbo Song" Chapter 16 4: "The landscapes of Guilin and Yangshuo (seriously, can only be mountains) are indeed very peculiar. ”

1. Square

is a special parallelogram.

One. That is, a group of parallelograms with equal adjacent sides and one angle is at right angles is called a square, also known as a regular quadrilateral.

2. Rectangle

A parallelogram with an angle that is a right angle is a rectangle. A rectangle is a special type of parallelogram, and a square is a special rectangle.

3. Diamond-shaped

Within the same plane, there is a group of parallelograms with equal adjacent sides that are rhombuses, and quadrilaterals with equal sides are rhombuses, the diagonal of the rhombus.

Bisected perpendicular to each other and bisected by each group of diagonals, the rhombus is an axisymmetric figure, an axis of symmetry.

There are 2, i.e., the straight line where the two diagonals are located, and the diamond is a central symmetrical figure.

4. Rectangle

It is a flat figure, which is a parallelogram with a right angle at one angle. A rectangle is also defined as a parallelogram with all four corners at right angles. A square is a special rectangle with four sides of equal length.

5. Triangle

It is a closed figure composed of three line segments that are not on the same straight line in the same plane, which are connected sequentially and have applications in mathematics and architecture.

Triangle, Square, Rectangle, Circle, Ellipse, Rhombus, Hexagon, Octagonal, Pentagon, Trapezoidal, Parallelogram, Heart, Pentagram, Heptagon, Semicircle, Cylindrical.

Pentagram, heart, square, rectangle, hexagonal, heptagon, triangle, pentagon, octagonal, round, ......

Pocket money. Pentagram, heart, square, rectangle, hexagonal, heptagon, triangle, pentagon, octagonal, ......

Triangle Square Rectangle Circle Oval Rhombus Hexagon Octagonal Pentagon Trapezoidal Parallelogram There is a repetition of understanding.

Rhomboid, in the same plane, there is a group of parallelograms with equal adjacent sides is a rhombus, the quadrilaterals with equal sides are rhombus, the diagonals of the rhombus are bisected perpendicular to each other and bisect each group of diagonals, the rhombus is an axisymmetric figure, there are 2 axes of symmetry, that is, the straight line where the two diagonals are located, and the rhombus is a central symmetrical figure.

- Rhombus, a set of parallelograms with equal margins is called a rhombus.

1. The rectangle has all the properties of a parallelogram; 2. The diagonal lines of the rectangle are equal; 3. The four corners of the rectangle are all 90 degrees; 4. The rectangle is an axisymmetric figure, and it is a center-symmetrical figure It has two symmetry axes, which are the straight line where the midpoint of each group of opposite sides is located; The center of symmetry is the intersection of two diagonals. Rhombus Definition: A set of parallelograms with equal adjacent sides is a rhombus.

Judgment: 1. A group of parallelograms with equal adjacent sides is a diamond; 2. Parallelograms with diagonal perpendicular to each other are diamond-shaped; 3. A quadrilateral with equal sides is a diamond. Nature:

1. The rhombus has all the properties of a parallelogram; 2. The four sides of the diamond are equal; 3. Each diagonal line of the diamond is divided into a group of diagonals; 4. The rhombus is a center-symmetrical figure and an axisymmetric figure. Square Definition: A group of parallelograms with equal adjacent sides and one corner being a right angle.

This is a rhomboid, which is unstable and is also a parallelogram.

The chess pieces are block-shaped, or they are prisms.

Polygon [ duō biān xíng ] Basic Definition of Raw Words.

duō biān xíng ]

A closed figure consisting of three or more line segments that are connected one after the other. Polygons are called trilaterals (i.e., triangles), quadrilaterals, pentagons, and so on according to the number of sides they have.

(Strange) shapes, (solid) shapes, (different) shapes.

A variety of shapes, which are in accordance with the textbooks.

Paid pass day by day, suddenly dizzy Tong Ren Tang.
