Erica plotted the three towns closest to her house on a graph with town a
a
at (9, 12), town b
b
at (9, 7) and town c
c
at (1, 1). she drew the triangle joining the 3 points. which lists the angles formed in size, smallest to largest?

Please plot these 3 points on graph paper.  This will result in a triangle with three different vertices.   Which vertex corresponds to the largest interior angle of the triangle?  to the smallest?  If you can answer these questions properly, then you'll pretty much have the answer to this question.  Be sure to arrange the sizes of the angles in ascending (increasing) order.
