Part A: Determining Latitude
1. Figure A represents Earth, with point B its
center. Locate the equator on the globe.
Sketch and label the equator on Figure A. Label the Northern
Hemisphere and Southern Hemisphere on Figure A.
2. On Figure A, make an angle by drawing a line from point A on the
equator to point B (the center of Earth). Then extend the line from
point B to point C in the Northern Hemisphere. The angle you have
drawn (aABC) is 45°. By definition of latitude, point C is located at
3. Draw a line on Figure A through point C that is also parallel to the
equator. What is the latitude at all points on this line? Record this
number on the line you draw.
4. Draw a line on Figure A from point D to point B. Using a protractor,
measure aABD on your paper. Then draw a line parallel to the
equator that also goes through point D. Label the line with its
5. How many degrees of latitude separate the latitude lines (or
parallels) on the globe that you are using? Record the degrees
