first of all, make a sketch of the two lines and point P ...
the set of all points 3 cm from P forms a circle of radius 3 cm about P.
sketch that circle.
now look ... how many points on that circle are equidistant from l and m?
Lines l and m are parallel and 4 cm apart. Point P lies on line l. What is the locus of points 3 cm from P and also equally distant from l and m?
a.) 1 point
b.) 2 points
c.) 1 line
d.) two lines
*Please explain if possible. Thanks for any help!*
