Compare Latitude and Longitude using a VENN Diagram. Start by drawing two large circles that overlap each other. In the middle where they overlap, put all the things they have in common (such as they both measure degrees of a circle). On the left circle put all the things that make latitude different from longitude (maximum degree, measure east and west of 0 degrees or north and south, where the zero line is located, lines that go vertical or horizontal on a map); then on the right circle put all the things that make longitude different.
Use appendix III, page 467 in text as well as Box 1.1 on page 9 to help you.
