directions. What method should be used to restore that lost corner?

a. single proportion measure
b. double proportion measure
c. two way proportion
d. four way record directions

2. Lengths of proportioned lines are comparable only when reduced to their

b. measured slope distance
c. true line length
d. cardinal equivalents

3. Choose the formula that shows proportion "P" determination.
