1. Mr. Calise Geometry Room 306 Unit A Section 1
Welcome Back!!
Hope you had a
Great summer!!!!!!!

2. Drill: Mon 8/27
Objective: Identify, name, draw, and apply basic facts of points, lines, segments, rays, and planes.
Look at the picture at right. List as many geometric terms as you can that are represented in the photo.

3. What is Geometry? Brain Pop Video
All other geometry is defined from points, lines, and planes

13. Notes(Vocab)
Points: have no size, often represented with dots, and named with a capital letter. C A B

14. Lines: have no thickness, and extend infinitely in two directions
Lines: have no thickness, and extend infinitely in two directions. Named with two points, or a cursive letter. l Y X

15. Collinear: points that are lying in the same line.
Non-Collinear: Not lying in the same line. A B C C A B

16. Planes: Extend infinitely in all directions
Planes: Extend infinitely in all directions. It is flat and has no thickness. There are two ways to name a plane.
To Name a plane you need 3 non-collinear points.
Coplanar: Points and lines that are in the same Plane.

17. Segments: Are parts of lines, they have two endpoints, and are named by using the two endpoints.

18. Rays: is a “half-line”. It has one endpoint and extends infinitely in one direction.
Opposite Rays: share the same endpoint and go in opposite directions.

19. Parallel Lines: are lines that are in the same plane and do not intersect. (Same Direction)

20. Parallel Planes: Two planes that never intersect.
Skew Lines: Lines that are in different planes (Different Directions and do not intersect)
