Task #1
Carlos finds the following definition of a reflection in a math book:
The reflection re about a line t takes each point Pont to itself and takes each point Q
not on to the point re(Q) such that l is the perpendicular bisector of Qre(Q).
Carlos does not find this definition very helpful. He says "the reflection about a line
sends each point to its mirror image on the other side of e."
a. In what ways is Carlos' definition of reflection more helpful than one from the math
book?
b. In what ways is the math book definition of reflection more helpful than Carlos'
definition?
