Copy of 1-2 Points, Lines, Rays, Segments & Planes
What are points, Lines, Rays, Segments & Planes and how do we name them?
#1
a. Give two other names for line ST and plane R. b. Name 3 points that are collinear. c. Name 3 points that are coplanar Example format for answering: a. Line QP
d. Give another name for segment GH. How can you tell if I am referring to line GH or segment GH and how are they different? e. Name all rays with endpoint J. How can you tell a ray from a line, or a segment? Which rays are opposite rays?
Find where lines and planes intersect and name them!
#2
