What are polygons?
Polygons are flat, closed shapes made of straight lines.
These lines are called pages, and the points that the pages meet are called cornerstones (single: vertices).
It’s bent.
The shape is closed (no gaps from all sides).
Hexagon
Page – A straight line that forms a polygon.
The second pinnacle – the corner where the sides meet.
Winkel – The space between both sides of the vertex. I have it.

Squares are regular polygons, with all four sides equal.
Example:
Scale corners have all sides and angles of varying length.
Some of the polygons do not enter.
Example:
Normal hexagons are convex.
Part of the “cave” format.
Example:
The star is concave. pentagon.
4 pages of special polygons.
All squares have 4 pages, but there are different types.
4 square pages and all angles are 90°
Example:
The opposite pages of the parallel diagram are the same and in parallel
Example: Slope rectangle
Trapezoid (or trapezoid) – One pair on the opposite side is parallel
Example: (n -2) 180°
(n = number of pages)
Example (4 seiten): (4-2) 360°
Here are some examples:
Real life examples of polygons
Triangular road signs, pyramids
Square chessboards, tiles
Rectangular mobile phones, books
Pentagon badges, pentagonal buildings
Hexagon honeycomb stop sign
How to identify polygons?
Ask yourself the following questions:
Is the shape flat? br>
Are all the sides straight?
br>
Is the shape closed?
If so, it’s a polygon! Hexagon
Example:
Triangular sandwich
Square
What do you call a polygon with the same page and all the correct angles?
Square.
Do polygons have curved pages?
No, just the page.
What is the sum of the inner angles of a triangle?
180°
