Name four points that are coplanar. How many of the planes contain points F and E? Are points A, B, and C coplanar?
There are three points on the line. Answer & Explanation. Refer to the figure. Lesson 1.1 points lines and planes answers key. 2 points determine a line. How many planes are shown in the figure? 1 Points, Lines and Planes Objective: I will be able to… entify and model points, lines, and planes as well as intersecting lines and planes generalizations about geometric properties. LESSON Example 2b Plane B. Defined term: explained using undefined terms and/or other defined terms.
D C B A M. LESSON Example 1 A. LESSON Example 1a A. Use the figure to name a plane containing point L. You can also use the letters of any three noncollinear points to name the plane. A flat surface with no thickness. LESSON Plane: made of points that extend infinitely in two directions, but has no height. LESSON What is this? A capital script letter can also name a plane. Usually represented by a dot and a capital letter. Points lines and planes ppt. Use the figure to name a line containing point K. Answer: The line can be named as line a. LESSON Example 3 Draw dots on this line for point D and E. Label the points. Name the geometric shape modeled by a 10 12 patio. AB l line l Point: a location with no dimensions.

LESSON Example 3 Answer: LESSON A. Answer: Points A, B, and D are collinear. Answer: There are two planes: plane S and plane ABC. LESSON Undefined Terms Line: made of points that extend in one dimension – no width or depth, but infinite length. What do an intersecting line and a plane have in common? Understanding points lines and planes. LESSON Example 3 Draw a line anywhere on the plane. Example 3 Draw a surface to represent plane R and label it.
AB C D D. LESSON Defined Term: items defined by means of undefined terms or previously defined terms. LESSON Try on your own! B. C. D. Example 3a A. Plane P. LESSON Example 2 A. Plane D contains line a, line m, and line t, with all three lines intersecting at point Z. Three noncollinear points determine and name a plane. Plane JKMplane KLMplane JLM Answer: The plane can be named as plane B. Stuck on something else? LESSON Undefined term: a term that is only explained using examples and descriptions Point: a location with no dimensions; it has no shape or size Line: made up of points and has no thickness or width (1 dimension); must have 2 points for a line Plane: a flat surface made up of points that extends infinitely in all directions (2 dimensions); must have 3 non-collinear points for a plane. There are 15 different three-letter names for this plane (any order). Use the figure to name a plane containing point Z.
