  1. Flatbush Avenue is the second longest thoroughfare entirely contained within the New York borough of Brooklyn. It starts at the Manhattan Bridge (which connects Brooklyn to Manhattan) and ends at the Gil Hodges Bridge (which connects Brooklyn to Queens). Although generally heading northwest/southeast, Flatbush Avenue wanders a bit. This plus the fact that there is no unified street grid in Brooklyn means that cross streets rarely intersect Flatbush Avenue at right angles. Using the protractor provided in the following diagrams, determine the angle of intersection between Flatbush Avenue and six different intersecting avenues and one intersecting street.
