2 A point represents a location, often denoted with a dot, although it has no length, width or thickness.

A line is named by listing two points that are on the line. For example, consider the line shown with the indicated points. How can this line be named?

Although it has no edges, we usually denote it with a 4-sided figure often labeled with a capital letter or 3 letters on the plane representing points on the plane not on the same line.

2 2 A point represents a location, often denoted with a dot, although it has no length, width or thickness. Usually represented with a capital letter, for example point P or P A line is an infinite set of points that extend endlessly in opposite directions. The line has no thickness. Its length is infinite. A line is named by listing two points that are on the line. For example, consider the line shown with the indicated points. How can this line be named? A B C A line is also sometimes named using a lower case letter A plane is a set of points that forms a complete flat surface and extends in all directions indefinitely. It has no thickness. Although it has no edges, we usually denote it with a 4-sided figure often labeled with a capital letter or 3 letters on the plane representing points on the plane not on the same line. Online: Sample Test Question: Although we have described a point, line, and a plane, they are considered to be undefined terms. These undefined terms are then used in the definition of other terms. A definition is a statement of precise meaning of a term. We must define a word or term in words that have been defined or accepted as undefined terms such as a point, line, or plane. Definition: A collinear set of points is a set of points all of which lie on the same straight line. Online Activity: Definition: A non-collinear set of points is a set of 3 or more points that do not all lie on the same straight line. Definition: A coplanar set of points is a set of points all of which lie on the same plane. Online Activity: Question: If you had a deck of playing cards in one stack on a table, what could you do to the stack of cards so that all the cards are coplanar?

Sample Test Question: 3 Sample Test Question: Choose the correct

Points F, A, L, I, C are coplanar. Choices: A. 1 and 2 only B.

3 Sample Test Question: 3 Sample Test Question: Choose the correct statement/statements. 1. Points F, A, L, I, C, G, E, O, and B are coplanar. 2. Points G, E, F, and A are coplanar. 3. O, A, and B are coplanar. 4. Points F, A, L, I, C are coplanar. Choices: A. 1 and 2 only B. 3 and 4 only C. 4 only D. 1 only Question: Which of today s terms describes the intersection of two planes?
