A trapezoid is any four-sided figure that has at least one pair of parallel sides. Pictured below is trapezoid ABCD whose side AD is parallel to side BC. Line m is the perpendicular bisector of side AD, with midpoint at E. Line m also bisects side BC with midpoint at F. a) Explain why line m must also be perpendicular to side BC.
b) What rigid motion could be used to show that AB=CD? Explain how the mapping would work.

Which statement accurately explains whether a reflection over the y-axis and a 270° counterclockwise rotation would map figure acb onto itself? a coordinate plane with figure acb with point a at 1, 1, c at 3, 4 and b at 5, 1 yes, a″c″b″ is located at a″(1, 1), c″(4, 3), and b″(1, 5) yes, a″c″b′ is located at a″(1, 1), c″(3, 4), and b″(5, 1) no, a″c″b″ is located at a″(1, 1), c″(4, 3), and b″(1, 5) no, a″c″b″ is located at a″(1, 1), c″(3, 4), and b″(5, 1)
