Final answer:
Without specific details, we can only explain that a sequence to show similarity of triangles typically involves a dilation to resize, a translation to reposition, and a reflection or rotation to reorient. The exact sequence would depend on the triangles' initial positions and orientations.
Step-by-step explanation:
To answer the student's question about describing a sequence of similarity transformations that shows ∆BAC is similar to ∆EAD, we would need additional information such as a diagram or description of the placement of the triangles. However, in a general sense, similarity transformations that can show one triangle is similar to another include a series of dilations, translations, rotations, and reflections.
For two triangles to be similar, one triangle must be able to be resized, repositioned, and reoriented to match the other triangle without altering the shape or the proportion of the sides. This means that their corresponding angles are equal and their corresponding sides are in proportion.
A sequence that could demonstrate triangle similarity, in general, would typically start with a dilation to resize the triangle, followed by a translation to shift it to the correct position, and finally a reflection or rotation to adjust its orientation. However, depending on the specific circumstances, fewer steps might be needed or the order could be different.
