Problem 2

Use a centimeter ruler. Copy the points $F . T .$ and $P$ from the diagram.
a. Draw a line to indicate all points equidistant from $F$ and $T$.
b. Draw a circle to indicate points $6 \mathrm{cm}$ from $P .$ If you don't have a compass, draw as well as you can freehand.
c. How many points are equidistant from $F$ and $T$, and are also $6 \mathrm{cm}$ from $P ?$
