Geometry - making a problem with the properties of lines and angles
Expert: Scott A Wilson - 10/30/2009
Question
is it impossible to make and solve a problem that uses at least six lines, one set of parallel lines, one perpendicular line, one vertical angle and one linear pair?
Answer
Lets play pick up sticks. Suppose they all dropped.
In the way they dropped, two of them were parallel and two were perpendicular.
There was also one pointing right at you (that's the vertical).
I'm not sure what is meant by a linear pair. Do you mean one on top of another?
Yet anyway, the question is, "How few sticks could there be?"
Answer: Three; two were parallel and were laying horizontically;
one was perpendicular to the first two, and was therefore vertical as well.
