1. Determine the theme and content: select a theme related to the polygon graphic area, such as "Exploring the area calculation method of different polygons" or "Comparing the area sizes of different polygons".
2. Drawing polygon graphics: Drawing polygon graphics on paper or using electronic drawing tools, which can include triangles, parallelograms, trapezoid, etc. Make sure that the drawn figures are accurate, and mark the side length or bottom edge and height of each figure.
3. Write a title and introduction: Add an attractive title to the tabloid, such as "The Mystery of Polygon Graphic Area" or "Calculation Method of Different Polygon Areas".
4. Add text content: Add relevant text content next to polygon graphics to explain the area calculation method of different polygons, which can be illustrated by simple formulas and examples. For each polygon, a formula for calculating its area can be listed.
5. Draw a table: If you need to compare the areas of different polygons, you can draw a table to display the data. List the names, side lengths or bottoms and heights of different polygons in the table, and the corresponding area values.
6. Add legends and notes: add legends and notes on the map to explain the characteristics and area calculation methods of different polygons. You can use colors or shapes to distinguish different polygon types. Finally, check whether the layout and typesetting of the whole tabloid are reasonable. Ensure that there is no overlap or interference between graphics, text and notes, and the overall style is consistent.
Polygon theorem:
The sum of the internal angles of 1 and n polygons is equal to (n-2) x180; This theorem applies to all planar polygons, including convex polygons and planar concave polygons.
2. In a plane polygon, the sum of the internal angles of the equilateral convex polygon and the concave polygon is equal. But spatial polygons are not applicable. Reversible function: edge of n polygon = (internal angle sum ÷180)+2; There are (n- 3) diagonal lines on one vertex of the N-polygon; N polygon * * * has n×(n-3)÷2= diagonal.
3. After the n- polygon passes through a vertex and leads out all diagonals, divide the polygon into n-2 triangles.
