Question

what were tri- rathas? ​

Answer 1

In Hindu temple architecture, a ratha is a facet or vertical offset projection on the plan of the sanctum and shikhara above, or other structure. It is generally carried up from the bottom of the temple to the superstructure.[1][2] The corners of each ratha touch notional circles on the plan of the temple, centred on the murti image in the sanctum. The sides are oriented along the main horizontal axis of the temple (normally running east-west) or at right angles to it, generating (except around the entrance to the sanctum) a multi-faceted plan that harmonizes the square and the circle, becoming more circular in overall shape as the number of rathas increases.
