If r1 , r2 , and r3 represent rotations from dn and f 1 , f 2 , and f 3 represent reflections from dn , determine whether r1 r2 f 1 r3 f 2 f 3 r3 is a rotation or a reflection.

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
