Question

how can a similarity transformation be used to determine that the aa criterion proves the dilated triangle abc is similar to triangle abc? (1 point) center the original triangle inside the dilated triangle and see if the side lengths are congruent by using the scale factor. translate the dilated triangle so one of its angles exactly matches the corresponding angle in the original triangle; repeat using a different pair of angles. find the angle measures of the original triangle and the dilated triangle, then compare proportionality of the ratio to the scale factor. reflect the triangle across the x - axis and check for symmetry among the triangles with respect to the x - axis.

Explanation:

To determine similarity via AA criterion, we need two pairs of congruent angles. The correct method is to translate the dilated triangle so one angle matches a corresponding angle in the original, then repeat for another pair. This checks two angle congruences (AA). Other options: centering and checking side congruence is for congruence, not similarity; checking angle measures and proportion is not the AA method; reflecting is about symmetry, not AA similarity.

Answer:

Translate the dilated triangle so one of its angles exactly matches the corresponding angle in the original triangle; repeat using a different pair of angles.
