Question

which transformation maps trapezoid abcd onto itself using a line of symmetry? use the drop - down menus to explain your answer. click the arrows to choose an answer from each menu. the line that passes through the midpoints of choose... is a line of symmetry of trapezoid abcd. trapezoid abcd is mapped onto itself if the figure is choose... the line of symmetry.

Explanation:

A trapezoid (specifically an isosceles trapezoid, as implied by the symmetry context) has a line of symmetry passing through the midpoints of its two parallel sides (bases). Reflecting the trapezoid over this line maps each point to its mirror image on the other side, resulting in the figure mapping onto itself.

Answer:

The line that passes through the midpoints of the two parallel sides (bases) is a line of symmetry of trapezoid ABCD. Trapezoid ABCD is mapped onto itself if the figure is reflected over the line of symmetry.
