  1. 1. Today’s Plan: Unit 1 - Geometry What makes a polygon?
  2. 2. Polygon
  3. 3. Polygon A polygon is a closed shape made of line segments (sides) connected endpoint to endpoint.
  4. 4. Polygon A polygon is a closed shape made of sides that connect endpoint to endpoint.
  5. 5. Polygon A polygon is a closed shape made of sides that connect endpoint to endpoint.
  6. 6. Polygon A polygon is a closed shape made of sides that connect endpoint to endpoint. Not a polygon

  14. 14. Polygons Sides connect at endpoints (can’t cross) Closed shape
  15. 15. Polygons Sides connect at endpoints (can’t cross) Closed shape The sides are line segments (no curves)
  16. 16. Polygons Sides connect at endpoints (can’t cross) Closed shape The sides are line segments (no curves)
  17. 17. Polygons Sides connect at endpoints (can’t cross) Closed shape The sides are line segments (no curves) At least three sides
  18. 18. Polygons Sides connect at endpoints (can’t cross) Closed shape The sides are line segments (no curves) At least three sides
  19. 19. Polygons Sides connect at endpoints (can’t cross) Closed shape The sides are line segments (no curves) At least three sides Only one inside
  20. 20. Polygons Sides connect at endpoints (can’t cross) Closed shape The sides are line segments (no curves) At least three sides Only one inside
