ETAKE (BINGHAM-Per.6-Math 8) 5
Dennis and Eduardo are studying transformations using triangles. Triangle ABC and triangle
DEF are both plotted on a coordinate plane. Dennis notices that if he rotates triangle ABC 90
degrees clockwise from the origin and then translates it down 4 units, the result is triangle
DEF. Eduardo says that he can first translate triangle ABC down 4 units and then rotate
triangle ABC 90 degrees clockwise from the origin in order to get triangle DEF. Is Eduardo
correct? Explain your answer and tell whether triangle ABC and DEF are congruent. ***HINT
Does order matter if there is a rotation in the list?
