# typeface.py
# By Chris Proctor and _________
# Contains one function for each letter in the English alphabet.
# Each function should draw its letter at a scale of `unit`, and then
# return back to the same position and heading where it started.
# Note: The `sqrt` function from math may be helpful--if you want to
# move the turtle along the diagonal of a square with side length x,
# the turtle should move a distance of sqrt(x)
