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.

Reflect the triangle across the x-axis and check for symmetry among the triangles with respect to the x-axis.

Center the original triangle inside the dilated triangle and see if the side lengths are congruent by using the scale factor.

Find the angle measures of the original triangle and the dilated triangle, then compare proportionality of the ratio to the scale factor.

Answer 1

Translate (and if needed rotate) the dilated triangle so one corresponding angle matches, then align a second corresponding angle. Matching two angles shows the triangles are similar by AA (dilation preserves angles).
