trilateral

We will probably never know what else Kerry told the Trilateral Commission behind closed doors.

We made chit chat and talked about The Trilateral Commission in general terms.

His body was trilateral: he had three legs, three arms, and six eyes, placed at equal distances all around his head.

"Trilateral" is from the Latin translation of the Greek tripleuros (three-sided).

Trilateral members, or waverers, are those which have three sides.

The circuit was trilateral, and to a considerable extent remains so.
