AVIATION
48.
Airplanes heading eastbound are assigned an altitude level that is
an odd number of thousands of feet. Airplanes heading westbound are assigned
an altitude level that is an even number of thousands of feet. If one airplane is
flying northwest at 34,000 feet and another airplane is flying east at 25,000 feet,
describe the type of lines formed by the paths of the airplanes. Explain your
reasoning.
STRUCTURES
For Exercises 49–51, refer to the drawing

simultaneously, or devices, such as printers, that
receive more than one bit of data at a time. Find two
other examples for uses of the word parallel in other
subject areas such as history, music, or sports.
CRITICAL THINKING
Suppose there is a line and a point P not on the line.
53. In space, how many lines can be drawn through P that do not intersect ?
54. In space, how many lines can be drawn through P that are parallel to ?
WRITING IN MATH
Answer the question that was posed at the beginning of
55.
the lesson.
How are parallel lines and planes used in architecture?
• a description of where you might expect to find examples of parallel lines and
parallel planes, and
• an example of skew lines and nonparallel planes.
