The image of trapezoid PQRS after a reflection across Line W Y is trapezoid P'Q'R'S'.

2 trapezoids are shown. Line W Y is the line of reflection. Line segment R R prime has a midpoint at point Z. Line segment S S prime has a midpoint at point X.

What is m?

45º
90º
180º

90º

Reason: A reflection across a line bisects and is perpendicular to each segment joining a point and its image. Z and X are midpoints on the line of reflection, so RZ (or SZ) is perpendicular to ZX (the reflection line). Therefore the marked angle m is a right angle (90°).
