1 Lesson 1: Points, Lines and Planes

2 » 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 line » Plane- flat surface made from points that has no depth and extends in all directions infinitely » Coplanar- points or lines on the same plane » Space- boundless, 3-D set of all points that contains lines and planes

3 » Step 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 crease » Step 3- Cut the folded flaps along the crease so that there are now 4 flaps

4 » Label the outside of the flap with the lesson number and title. » Inside the flap create a grid with 7 columns and 4 rows.

5 ModelDrawnNamed ByFactsWords/ Symbols Examples Point As a dotA capitol letter A point has neither size nor shape point P Line With an arrowhead at both ends Two letters representing points on the line- or the script letter There is exactly 1 line through any two points line n line AB line BA Plane As a shaded, slanted, 4- sided figure A capital script letter or by any three letters of non- collinear points There is exactly 1 plane through any three non- collinear points plane S plane XYZ plane XZY plane ZXY plane ZYX plane YXZ plane YZX P A B X Y Z S n

6 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.

7 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.

9 A. How many planes appear in this figure? B. Name three points that are collinear. C. Are points A, B, C, and D coplanar? Explain.
