### Points, Lines & Planes Powerpoint

1. 1. Points, Lines & Planes Knox Baggett Geometry
2. 2. Introduction <ul><li>Points, Lines & Planes are the building blocks to understanding Geometry. </li></ul><ul><li>They are found in many places in real life. </li></ul>
3. 3. Characteristics of a Point <ul><li>In Geometry, a point is a location without any shape. </li></ul><ul><li>Points are named with a capital letter. </li></ul><ul><ul><li>Example: Point A lies on plane B. </li></ul></ul><ul><ul><li>Points are drawn as a dot. </li></ul></ul>
4. 4. Points <ul><li>The picture below is an example of a group of points. </li></ul>Point C
5. 5. Characteristics of Lines <ul><li>A line contains points </li></ul><ul><li>Lines have no thickness or width </li></ul><ul><li>There is exactly one line through any 2 points. </li></ul><ul><li>The intersection of two lines is a point. </li></ul>
6. 6. Lines Line m Line f The intersection of lines m and f create a point. Point T
7. 7. Characteristics of Planes <ul><li>In geometry, a plane is a flat surface made up of points. </li></ul><ul><li>Planes have no depth </li></ul><ul><li>Planes extend infinitely in all directions </li></ul><ul><li>The intersection of two planes is a line. </li></ul>
8. 8. Planes <ul><li>Planes are identified using a Capital Italicized Letter. </li></ul><ul><li>Example: Plane R </li></ul><ul><li>Planes can also be identified using 3 NON COLLINEAR Points </li></ul>Plane R
