Name a line and a plane in the picture below:
LEQ: What are segments and rays and how are they named? What are parallel lines and planes?
Segment: part of a line, has exactly two endpoints Drawing Symbol Name: “segment AB”
Ray: part of a line, has exactly one endpoint with other end extending in opposite direction Drawing Symbol Name: “Ray AB”
Opposite rays: Two rays that share a common endpoint and extend in opposite directions
Parallel lines: Two identical lines that never intersect. Symbol: ll m ll f
Skew lines: Two lines that never intersect but are not parallel.
Parallel Planes identical planes that don’t intersect Planes ABCD and EFGH are parallel
Line symbol:
Segment Ray Opposite rays Skew Lines Parallel Planes Parallel Lines
Name all segments and rays in the figure. Name any opposite rays
Name all the parallel planes in the figure below:
Name all segments parallel to AE. Name all segments skew to AE. Name all segments parallel to DC. Name all segments skew to DC. A C B D F H E G
P : 1-15 odd, 16-23, 38
