1-1 Points, Lines, and Planes A _____________ is simply a location that has no dimension.

A _________is made up of points. It has no thickness or width and stretches in one dimension.

A plane is a flat surface that is made up of points. It stretches without bound in two dimensions.

Points that lie on the same line are called __________________ points. Similarly, points that do not lie on the same line are called ________________ points.

Points that lie on the same plane are called __________________ points. Similarly, points that do not lie on the same plane are called ________________ points.

Points, lines, and planes are called ________________terms. This means that they can only be explained using examples and descriptions.

In the picture to the right, circle a point in RED. What is the name of the point?

Circle a line in BLUE. What is the name of the line?

Circle a plane in GREEN. What is the name of the plane?

Circle the intersection of lines l and m in PURPLE. What is its name?

Circle a point that is not collinear with points A, B, and C in ORANGE.

Draw and name a point that is noncoplanar with plane P in PINK.

ABC Book: Chapter 1Come up with words from every letter of the alphabet that pertain to your knowledge of the contents of Chapter 1. Each word MUST be either a vocabulary word we have used (i.e. Vertical angles for V) or objects that “look like” words that we have studied (i.e. Stop sign for S). After you have determined all 26 words, you must complete an ABC book. IMPORTANT: Each letter of the alphabet must be illustrated as you see below:

**The words complementary, supplementary, vertical angles, distance, midpoint, and bisector must be used. You must show a definition and an example problem completely worked out for each of these.**
