3. Objective SWBAT name and identify points, collinear points, lines, line segments, planes, parallel lines, skew lines, and parallel planes.

4. Let’s start thinking! Draw a square. Label the square ABCD Can you identify anything about the square? (i.e. points, lines) Now make that square into a cube. Can you identify any parallel lines? Look at this picture of the trolley on St. Charles Ave. Do you see any parallel lines, points of intersection?

5. Terms Point: a location; it has no size, is represented by a small dot and is named by a capital letter Lines: are series of points that extends in two opposite directions; they are named using any two points on the line & the order does not matter. Collinear points: Points that lie on the same line.

6. Terms Plane: – a flat surface that has no thickness. – Has many lines and extends without end in the directions of all its lines. – named with a single capital letter or AT LEAST three of its noncollinear points. Coplanar (points and lines): when points and lines lie in the same plane.

7. Terms Line segment: a part of a line consisting of two endpoints and all points between them Ray: the part of a line consisting of one endpoint and all the points of the line on one side of the endpoint Opposite rays: two collinear rays with the same endpoint; opposite rays always form a line.

8. More terms Parallel lines: coplanar lines that do not intersect Skew lines: noncoplanar, which means they are not parallel and do not intersect. Parallel planes: planes that do not intersect.

9. Postulates Through any two points, there is exactly one line. – i.e. Points can be collinear even if the line is not drawn in the figure. If 2 lines intersect, then they intersect in exactly one point. If 2 planes intersect, then they intersect in exactly one line. Through any 3 noncolinear points, there is exactly one plane.
