Concept Check
1. Explain how to construct a segment between two parallel lines to represent the
distance between them.
OPEN ENDED
Make up a problem involving an everyday situation in which
2.
you need to find the distance between a point and a line or the distance between
two lines. For example, find the shortest path from the patio of a house to a
garden to minimize the length of a walkway and material used in its
construction.
3. Compare and contrast three different methods that you can use to show that
two lines in a plane are parallel.
