Activity (continued from previous page) 5. Select Skew lines. Drag the plane around to see different views. Then click New line several times, dragging the plane each time. A. The two lines shown each time are skew. Do skew lines ever intersect? B. Click New plane a few times. How many of the lines lie in the new plane? C. In your own words, describe skew lines. 6. Click New example several times. For each new example, click New plane. A. Are skew lines ever in the same plane? B. Does a pair of skew lines define a plane? Explain. 7. Neither parallel lines nor skew lines ever intersect. What are the differences between parallel lines and skew lines? 8. Can two lines that lie in the same plane be anything but intersecting or parallel? Explain. 9. The figure below contains several different pairs of intersecting, parallel, and skew lines. A. Name three different pairs of intersecting lines. B. Name three different pairs of parallel lines. C. Name three different pairs of skew lines.Activity: E !!| E' I _ Exaggrtmrlinee 0 Select Intersecting lines. 1. Click on New lines several times. Drag the plane around as needed to view the lines. A. The lines Intersect. How many points do the lines have in common? B. Click New plane a few times. Does the plane change? C. In your own words, describe intersecting lines. 2. Click New example several times. For each new example. click New plane. A. Is it possible for more than one plane to contain a pair of intersecting lines? Explain. B. Does a pair of intersecting lines dene a plane? Explain. 3. Select Parallel lines. Drag the plane until it appears to be nearly at. Then click New lines several times, dragging the plane each time. A. The lines are mild. How many points do parallel lines have in common? B. Click New plane a few times. Does the plane change? C. In your own words, describe parallel lines. 4. Click New example several times. For each new example. click New plane. A. Is it possible for more than one plane to contain a pair of parallel lines? Explain. B.
