Question

hüseyin was able to m quadrilateral efgh onto ejgk using a vertical stretch. hüseyin concluded: \i was able to map quadrilateral efgh onto quadrilateral ejgk using a sequence of rigid transformations and dilations, so the figures are similar.\ what error did hüseyin make in his conclusion? choose 1 answer: hüseyin used a vertical stretch, so the quadrilaterals arent similar. the quadrilaterals are mapped onto each other, so they are congruent, not similar. there is no error. this is a correct conclusion.

Explanation:

Similarity in geometry requires that corresponding angles are equal and corresponding sides are in proportion. A vertical stretch (a non - uniform scaling in the vertical direction) changes the shape in a way that the side - length ratios are not consistent in all directions. Rigid transformations (translations, rotations, reflections) preserve shape and size, and dilations (uniform scalings) preserve shape. But a vertical stretch is not a dilation (since dilation is uniform in all directions). So, using a vertical stretch means the figures are not similar.

Answer:

A. Hüseyin used a vertical stretch, so the quadrilaterals aren't similar.
