What are some things in the shape of a pentagram?

Starfish.

It is echinoderms.

The most representative category of structural physiology. The body is flattened, mostly symmetrical with five radiations, and the demarcation between the body disc and the wrist is not obvious. When living, the mouth faces down, and the mouth faces up. The ventral side of the wrist has a step groove, and the groove protrudes from the tube foot. The bone plate of the endoskeleton is used to connect the tissue.

Connected, flexible and bent. The body surface has spines and fork spines, which are protrusions of bones.

The membranous vesicular protrusions protruding from between the plates of the bone are covered with epithelium, lining the epithelium of the body cavity, and its inner lumen is connected to the secondary body cavity, called the skin gills, which have the effect of respiration and the diffusion of metabolites to the outside world. The water pipe system is well developed. Ontogeny of transfeathered brachial larvae and brachycarpal larvae.

There are 1,600 species and 300 fossil species, which are widely distributed in sandy seabed, soft mud seabed, coral reef and ocean at various depths.

Our national flag is a five-pointed star, and the stars on it represent our masses surrounding the Communist Party, and I believe that under their leadership, the Communist Party can prosper day by day and live better and better.

The pentagram has 10 triangles. There is a triangle in each of the five vertex corners, for a total of 5 apex triangles; Any two non-adjacent apex triangles plus the regular pentagon in the middle can form a triangle, and there are 5 such large triangles; 5+5=10。

For example, there are 4 triangles on each side of a pentagon, a total of 5*4=20.

There are 5 triangles formed by the adjacent sides of the pentagon.

Plus 10 with a pentagram inside.

Total: 35.

A five-pointed star is a type of star with five sharp corners drawn in five straight lines. The word "pentagram" comes from the Greek word and probably means "five straight lines" or "five lines". The meaning of the Chinese "five-pointed star" is obvious, referring to the shape of a star with five horns.

However, the Chinese "five-pointed star" does not necessarily mean a "standard" five-pointed star. The Chinese term "five-pointed star" sometimes refers to all star-shaped objects with five horns.

The big five-pointed star in the national flag represents the Communist Party of China, and the four small five-pointed stars represent the four classes of workers, peasants, petty bourgeoisie, and national bourgeoisie. The flag is red, symbolizing the revolution, and the star is yellow, indicating that the Chinese nation is a yellow race. The five five-pointed stars are intertwined and intertwined, symbolizing the unity of the Chinese people.

Each small star has a sharp angle facing the center point of the big star, indicating the centripetal meaning of the people to the party.

The pentagram has 10 triangles. The outer five corners form five small triangles, the middle pentagons, and each inner corner can form five large triangles. A triangle is a closed figure composed of three line segments in the same plane that are not on the same straight line, which are connected sequentially "at the beginning and end", which has applications in mathematics and architecture.

Common triangles are divided into ordinary triangles (the three sides are not equal) and isosceles triangles (isosceles triangles with unequal waists and bases, and isosceles triangles with equal waists and bottoms, that is, equilateral triangles). According to the angle, there are right-angled triangles, acute triangles, obtuse triangles, etc., among which acute triangles and obtuse triangles are collectively referred to as oblique triangles.

Relationships between graphs

Graphics refer to the space fragments bounded by contours in two-dimensional space, and a number of spatial shapes can be divided into contours in a two-dimensional space.

Graphics are different from marks, signs and patterns, it is not a simple symbol, nor is it a decoration for the purpose of aesthetics, but a deliberate form of portrayal and expression of a combination of one or more visual elements under the control of a specific ideology. It is a visual form that is different from words, words, and language, and can be reproduced in large quantities by various means, and it is a visual form of disseminating information.

The pentagram is made up of five horns and has three meanings:

1. The pentagram usually represents the meaning of victory.

2. In ancient Greece and Babylon, the pentagram was a symbol of magic and a symbol for non-Jews.

3. In Japan, the pentagram is considered to be the bellflower mark of the sunny.
