Construction – Intersecting Planes • Label one index card as Q and another as R. • Hold the two index cards together and cut a slit halfway through both cards. • Hold the cards so that the slits meet and insert one card into the slit of the other. Use tape to hold together. • Where the two cards meet models a line. Draw the line and label two points, C and D, on the line.
Analyze • Draw a point F on your model so that it lies in Q but not in R. Can F lie on DC? • Draw a point G so that it lies in R, but not in Q. Can G lie on DC? • If point H lies in both Q and R, where would it lie? Draw point H on your model. • Draw a sketch of your model on paper. Label all points, lines, and planes appropriately.
