  1. Bellringer Grab a textbook from the shelf then discuss with your shoulder the following situation… • Why does a four-legged chair sometimes wobbles, but a three legged chair never wobbles???

  2. Points, Lines, and Planes August 20, 2010

  3. Objective: • I will represent simple geometric shapes like points, lines, segments, rays, and angles using proper identification.

  4. Point • P Drawn: as a dot Named by: a CAPITAL letter Facts: A point has neither shape nor size Words/Symbols: point P

  5. Line n B A Drawn: with an arrowhead at both ends Named by: the letters representing two points on the line or a lowercase script letter Facts: There is exactly one line through any two points Words/Symbols: linen, line AB or , line BA or

  6. Plane T Y X Z Drawn: as a shaded, slanted 4-sided figure Named by: a capital script letter or by the letters naming three noncollinear points Facts: There is exactly one plane through any three noncollinear points Words/Symbols: plane T, plane XYZ, plane XZY, plane YXZ, plane YZX, plane ZXY, plane ZYX

  7. Write Rally Robin Students take turns stating and writing responses or solutions. Record answers on one sheet of paper.

  8. Write Rally Robin • Students take turns stating and writing responses or solutions. Record answers on one sheet of paper.

  9. Use the figure to name a line containing point A E l D C B A N

  10. Use the figure to name a plane containing point C E l D C B A N

  11. Name the line of intersection

  12. In review… There are 3 basic terms in geometry Point, Line, and Plane How do we model them? Draw them? Name them? And write them? It’s important…
