Transcripts - Polygons #2

  • 1. Polygons What are they?
  • 2. Polygons <ul><li>There are both irregular and regular polygons </li></ul><ul><li>Polygons are shapes with a face, three or more sides and is a closed figure </li></ul><ul><li>There are also polygons called convex and concave </li></ul><ul><li>Polygons come in many different shapes </li></ul><ul><li>Although shapes that are round like a circle (or shapes that do not have all straight lines) are not polygons </li></ul>
  • 3. Regular Polygons <ul><li>Regular polygons have equal sides and angles all the way around </li></ul>Regular Triangle Irregular Polygons <ul><li>Irregular polygons have unequal sides although some irregular polygons have equal angles </li></ul>Irregular Heptagon Rectangle (irregular)
  • 4. Triangle Pentagon Hexagon Heptagon Octagon Nonagon Decagon Undecagon Dodecagon Tridecagon Tetradecagon Pentadecagon Trapezoid Right Triangle Parallelogram Rectangle Regular Polygons Irregular Polygons s = sides 3 s 5 s 6 s 7 s 8 s 9 s 10 s 11 s 12 s 13 s 14 s 15 s 4 s 3 s 4 s 4 s
  • 5. Concave Polygon <ul><li>Convex polygons are shapes that curve out of a usual shape (or just does not have a dent in it) </li></ul><ul><li>Concave polygons are shapes that curve inward (if you can draw a straight line from inside one part of the shape going out of the shape then inside again to the other side, it is concave) </li></ul>Convex Polygon 1- regular triangle 2- irregular hexagon
