1. 1.2Points, Line and Planes 1.3 Measuring Segments

6. 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.

7. Analyze 1.Draw a point F on your model so that it lies in Q but not in R. Can F lie on DC? 2.Draw a point G so that it lies in R, but not in Q. Can G lie on DC? 3.If point H lies in both Q and R, where would it lie? Draw point H on your model. 4.Draw a sketch of your model on paper. Label all points, lines, and planes appropriately.

10. Q : Is the following statement true? “Through any line and a noncollinear point, there is exactly one plane.” Explain.

17. 22. What is the measure of PR if Q is the midpoint of PR? 14x + 2 6 – 3x  P Q R
