4. Lesson 1 Ex1 Name Lines and Planes A. Use the figure to name a line containing point K. Answer: The line can be named as line a. There are three points on the line. Any two of the points can be used to name the line.

5. Lesson 1 Ex1 Name Lines and Planes B. 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. plane JKMplane KLMplane JLM Answer: The plane can be named as plane B.

6. Lesson 1 Ex1 Name Lines and Planes The letters of each of these names can be reordered to create other acceptable names for this plane. For example, JKM can also be written as JMK, MKJ, KJM, KMJ, and MJK. There are 15 different three-letter names for this plane.
