3. In your own words, describe the following terms point, line, plane, line segment, and ray

4. Points, Segments, Lines, Angles, and Planes

5. I Can...
I can draw points, lines, line segments, and rays. I can identify these in two-dimensional figures.

6. Vocabulary Points Lines Planes Parallel/Perpendicular
Collinear/Coplanar
Skew Lines

7. Point A point is like a dot, and is named by one letter. M
Tip of a pencil M

8. Line
A line is an infinite set of points that expand in both directions. n A B
Pretend this road extends forever.

9. Line Segment
A line segment is part of a line, defined by two endpoints. C D

10. Ray
A ray is part of a line with one endpoint. It extends infinitely in one direction. C D
Sun Ray

11. Plane
A plane is the set of all points that form a flat surface. It extends in all directions infinitely.

12. Intersecting Lines
Two or more lines that meet at a point. F

13. Parallel Lines
Two or more lines that never intersect.

14. Perpendicular Lines
Two lines that intersect and form RIGHT angles.

15. Collinear Points
Collinear Points are points that lie on the same line.

16. Coplanar Points
Coplanar Points are points that lie on the same plane

17. Planes intersect at a
line.
Skew lines are lines that
do not intersect, are not
parallel, and do not lie in the
same plane.

18. A Line and Plane Intersecting

19. In Summary Planes intersect at a line Lines intersect at a point
A line and a plane intersect at a point
Skew lines are not parallel, do not intersect, and are not on the same plane
