  1. 1.6 – Classify Polygons

  2. Polygon: 1. Has at least 3 sides 2. No sides overlap 3. No curved sides

  3. Line segment forming the polygon Side: M Q T R S

  4. Point where two sides meet Vertex: M M T Q S T R Q R S

  5. Consecutive Sides: Two sides that share a point, one after the other M Q T R S

  6. Segment that joins two nonconsecutive sides Diagonal: M Q T R S

  7. triangle ABC quadrilateral Quad BDAC pentagon Pent ADECB B B D A A C D B A C C E

  8. triangle ABC quadrilateral Quad BDAC pentagon Pent ADECB hexagon Hex heptagon Hept octagon Oct nonagon decagon 11-gon ? Extra Credit! dodecagon n-gon

  9. Convex: Passes the rubberband test Concave: Not convex! Think of a cave going inward!

  10. State whether the shape is a polygon. If yes, is it concave or convex? If no, why not? Yes, Concave or Convex OR No, _________________ Curved side

  11. State whether the shape is a polygon. If yes, is it concave or convex? If no, why not? Yes, Concave or Convex OR No, _________________

  12. State whether the shape is a polygon. If yes, is it concave or convex? If no, why not? Yes, Concave or Convex OR No, _________________

  13. State whether the shape is a polygon. If yes, is it concave or convex? If no, why not? Yes, Concave or Convex OR No, ____________________ Overlaps

  14. All sides are congruent All angles are congruent All sides AND all angles are congruent

  15. Classify the name of the polygon by the number of sides. Is the polygon equilateral, equiangular, or regular? Explain your reasoning. Hexagon Regular All sides and angles 

  16. Classify the name of the polygon by the number of sides. Is the polygon equilateral, equiangular, or regular? Explain your reasoning. quadrilateral Regular All sides and angles 

  17. Classify the name of the polygon by the number of sides. Is the polygon equilateral, equiangular, or regular? Explain your reasoning. Octagon Equiangular All angles , but not all sides

  18. Classify the name of the polygon by the number of sides. Is the polygon equilateral, equiangular, or regular? Explain your reasoning. decagon equilateral All sides , but not all angles

  19. Classify the name of the polygon by the number of sides. Is the polygon equilateral, equiangular, or regular? Explain your reasoning. Heptagon Regular All sides and angles 

  20. Classify the name of the polygon by the number of sides. Is the polygon equilateral, equiangular, or regular? Explain your reasoning. Quadrilateral Equilateral All sides , but not all angles

  21. 3. The lengths (in feet) of two sides of a regular quadrilateral are represented by the expressions 8x – 6 and 4x + 22. Find the length of a side of the quadrilateral. 8x – 6 = 4x + 22 8x – 6 4x – 6 = 22 4x + 22 4x = 28 x = 7 Side Length = 8(7) – 6 = 50ft

  22. HW Problem # 39 3x + 12 = 20 – 5x 8x + 12 = 20 8x = 8 x = 1 Side Length = 3(1) + 12 = 15mm  7 sides = 105mm
