Transformation on the Coordinate Grid

Two trapezoids are shown on the coordinate grid. Which sequence of transformations shows that the two trapezoids are congruent?

• Translate Trapezoid 1 down 2 units, then reflect the resulting figure across the y-axis.

• Translate Trapezoid 1 to the right 2 units, then translate the resulting down 2 units.

• Translate Trapezoid 1 to the right 2 units, then reflect the resulting figure across the x-axis.

• Reflect Trapezoid 1 across the x-axis, then reflect the resulting figure across the y-axis.
