2. I CAN: Identify, draw, and name points, lines, and planes.
Identify when objects are collinear or non-collinear and coplanar and non-coplanar.
Identify, draw, and name segments, endpoints, rays, and opposite rays.
Define the term Postulate.
Identify the intersection of geometric objects.
Make sense of the 5 postulates regarding points, lines, planes, and their intersections (see pages 7 – 8 of text)

3. What is Geometry?

4. Undefined Terms
A term that cannot be defined by using other figures.

5. Undefined Terms
I CAN:
Identify, draw, and name points, lines, and planes.

6. Collinear and Coplanar
I CAN:
Identify when objects are collinear or non-collinear and coplanar and non-coplanar.

7. Example Name a point. Name a 2 lines. Name a plane.
Are Point E and Point C collinear? Why are why not?

8. More definitions I CAN:
Identify, draw, and name segments, endpoints, rays, and opposite rays.
