Final answer:
Greek and Roman architecture were similar in using fluted columns with Doric, Ionic, and Corinthian capitals as decorative and structural elements in temples and other buildings.
Step-by-step explanation:
One way that Greek and Roman architecture were similar is that both used columns to decorate buildings. Greek and Roman temples often included the fluted columns with architectural styles such as Doric, Ionic, and Corinthian capitals to top and decorate their columns.
While the Greeks primarily used these orders for their temples and public buildings, the Romans adopted and adapted these orders to suit a wider range of structures, including Roman basilicas, public spaces, and other important buildings.
