Lesson 1.3 AIM: Points, Lines, and Planes DO NOW: Use the isometric grid to draw the following figure.

DO NOW Draw this image on the isometric dot paper provided.

Identifying Collinear Points a. Are points E, F, and C collinear? And what line are they on? Yes, line m. b. Are points E, F, and D collinear? No. c. Why are there arrow points on the lines? They indicate the lines go on forever.

Identifying Planes a. Name the plane represented by the top. EAB, ABF,BFE,or FEA all work. b. Name the plane represented by the front. DAB, ABC, BCD, or CDA all work. c. What is the intersection of EFB and BCG? Line FB d. What is the intersection of ABC and ADH? Line AD
