Demonstrate how to sketch the intersection of lines, planes, a line intersecting a plane at a point, a line parallel to a plane…
Represent the postulate that two lines intersect at a point with sketches.
Represent the postulate that the intersection of two planes is a line with sketches.
Demonstrate how to construct a line perpendicular to a line at a given point.
Demonstrate how to construct a line perpendicular from a given point to a line.
This packet should help a learner seeking to understand the intersections of lines and planes through sketches.
This video explains how to sketch the intersection of lines, and planes, how to sketch lines parallel to planes, and how to sketch the intersection of a line and a plane.
This video explains what intersecting lines are, shows how they intersect at a point, and presents several theorems regarding the angles created by the intersecting lines.
