Question

which vertex is the center of dilation?
options: a, c, d, e, b (with a triangle diagram showing vertices a, b, c and points d, e inside the triangle)

Explanation:

The center of dilation is the fixed point from which all points are scaled. In the diagram, lines connecting corresponding vertices (C to D, B to E) meet at vertex A, confirming it as the dilation center.

Answer:

A. A
