The correct features used in classic Greek temples include:
- They have symmetry, simple shapes, beauty, order, and harmony.
- They have a triangular pediment and horizontal frieze along the roofline.
- They have Doric, Ionic, and Corinthian columns.
The statement "They were built using arches to support the roof" is not correct, as traditional Greek temples typically did not use arches; they primarily utilized post-and-beam construction.
