1Chapter 1: Tools of Geometry Lesson 1: Points, Lines and PlanesChapter 1: Tools of Geometry
2Definitions Point- represents a location Line- made up of points and has no thickness or width, extends infinitely at both ends (cannot be measured)Collinear- points on the same linePlane- flat surface made from points that has no depth and extends in all directions infinitelyCoplanar- points or lines on the same planeSpace- boundless, 3-D set of all points that contains lines and planesDefinitions
3Step 1- fold the construction paper in half both by width and length (hamburger and hotdog) Step 2- Unfold the paper and hold width wise, fold in the ends until they meet at the center creaseStep 3- Cut the folded flaps along the crease so that there are now 4 flapsChapter 1 Foldable
4Upper Left flap- Lesson 1.1 Points, Lines and Planes Label the outside of the flap with the lesson number and title.Inside the flap create a grid with 7 columns and 4 rows.
5Copy the notes into the foldable.

6Examples A. Use the figure to name a line containing point K. B. Use the figure to name a plane containing point L.C. Use the figure to name the plane two different ways.Examples
7Examples A. Name the geometric shape modeled by a 10 12 patio. B. Name the geometric shape modeled by a water glass on a table.C. Name the geometric shape modeled by a colored dot on a map used to mark the location of a city.D. Name the geometric shape modeled by the ceiling of your classroom.Examples
