FC: Shapes and Designs | Polygons
1: Introduction | In this project you will learn lots about many different polygons, sides, angles, and much more. I will show you real world examples of shapes all around us everyday. Hopefully you can learn something new from this project. Enjoy!
2: Triangle | ~All Triangles have an angle sum of 180* | ~Every Triangle has 3 sides and 3 vertices. | ~There are many different types of Triangles. | Acute triangles which have an angle of less than 90*. | Obtuse triangles which have an angle with more than 90*. | Right Triangles which have an angle of exactly 90* | Isosceles Triangles which have 2 sides of equal length.
3: Scalene Triangles which have no sides of equal length. | Equilateral Triangles which have all sides of equal length. | ~On a regular equilateral triangle all interior angles are 60* | Regular Triangle- | Irregular Triangle--
4: Quadrilaterals | ~All Quadrilaterals have am angle sum of 360* | ~All Quadrilaterals also have 4 sides and 4 vertices. | Square--
5: Non-Square Rhombus-- | Irregular Quadrilateral-- | <---- Non-Square Rectangle | <======= | | |
6: Pentagon | ~All pentagons have 5 sides and 5 vertices. | ~All pentagons have an angle sum of 540* | ~Regular Pentagon- A Regular Pentagon has 5 sides of equal length (all sides equal). | ~Irregular Pentagon- An Irregular Pentagon has 5 sides that are NOT all of equal length.
7: ~Regular Pentagon- | ~Irregular Pentagon-
8: Hexagon | -All Hexagons have 6 sides and 6 vertices. | -The angle sum of any Hexagon is 720 degrees. | -On a regular hexagon all interior angles are 120 degrees.
9: Regular Hexagon-- | Irregular Hexagon--
10: Octagon | -All Octagons have 8 sides and 8 vertices. | -The angle sum of all Octagons is 1,080* | -All interior angles of a Regular Octagon are 135*
11: Regular Octagon- | Irregular Octagon-
12: Decagon | -All Decagons have 10 sides and 10 vertices. | -The angle sum of a Decagon is 1,440* | -All interior angles of a regular Decagon are 144*.
13: Regular Decagon | Irregular Decagon
