1 Lesson 1-1 Points, Lines, and Planes

2 Ohio Content Standards:

3 Formally define geometric figures.

4 Ohio Content Standards: Formally define geometric figures. Recognize and explain the necessity for certain terms to remain undefined, such as point, line and plane

5 Vocabulary:

6 Vocabulary: Point:Point:

7 Vocabulary: simply a location

8 Vocabulary: Line:Line:

9 Vocabulary: made up of points and has no thickness or width

10 Vocabulary: Collinear:Collinear:

11 Vocabulary: points on the same line

12 Vocabulary: Plane:Plane:

13 Vocabulary: flat surface made up of points

14 Vocabulary: Coplanar:Coplanar:

15 Vocabulary: Points that lie on the same plane

16 Use the figure to name each of the following:

17 J L K M

18 a line containing point K J L K M

19 Use the figure to name each of the following: a line containing point K a plane containing point L J L K M

20 Name the geometric shape modeled by each object.

24 Vocabulary:

25 Vocabulary: Undefined terms:Undefined terms:

26 Vocabulary: terms only explained using examples and descriptions

27 Draw and label a figure for each relationship.

28 plane R contains lines AB and DE, which intersect at point P. Add point C on plane R so that it is not collinear with AB or DE.

29 Draw and label a figure for each relationship. plane R contains lines AB and DE, which intersect at point P. Add point C on plane R so that it is not collinear with AB or DE. QR on a coordinate plane contains Q(-2, 4) and R(4, -4). Add point T so that T is collinear with these points.
