Question

an architect makes a small - scale model of a building prior to construction. the model and the completed structure are an example of similarity translational symmetry reflectional symmetry rotational symmetry

Explanation:

Similarity in geometry means two figures have the same shape but not necessarily the same size. A building model and the actual building have the same shape but different sizes. Translational, reflectional, and rotational symmetries refer to specific types of rigid - motion symmetries which are not applicable here as the main relationship is about shape - size proportionality.

Answer:

similarity
