Practice with Points, Lines, and Planes

Part 1 Part 2: Intersections between two lines

In the box above: [br]Show the intersection of two lines. Remember that a line is determined by two points, so start by adding two points before drawing a line between them.[br][br]What is the intersection of two lines?

A point A ray A line A plane

Part 3 Part 3: Intersections of a plane with a line

Take some time to move around the graphic above so that you understand how the figures are intersecting. [br][br]Where does line [math]\longleftrightarrow ED[/math] intersect plane [i]P[/i]?

Part 4

Take some time to move around the graphic above so that you understand how the figures are intersecting. [br][br]In the image above, where does line [math]\longleftrightarrow ED[/math] intersect plane [i]P[/i]? (where do they overlap?)

The intersection is all of Plane P The line is on the plane, so the intersection is all of Line ED They only share Point E They only share Point D

Part 5 Part 5: Intersecting Planes

Take some time to move around the graphic above so that you understand how the figures are intersecting. [br][br]Where does plane [i]A [/i]intersect with plane [i]B[/i]?
