Triangle pqr has vertices at the following coordinates : p(0,1) q(3,2) r(5,-4) . determine wether or not triangle pqr is a right triangle . show all calculations for full credit .

STATEMENT                              REASON  

1. BC = EF                                    1. Given

2. AB + BC = AC                         2. Betweenness

3. AC > BC                                  3. Def. of segment inequality

4. AC > EF                                   4. Def. of congruent segments
