Triangle shape with 3 bright lights at each corner,moved slow, disappeared when it got above us.

The object had no sound, no blinking lights,moved very slow, no trail. It was brighter than the surrounding stars. When it was above us, it disappeared. Duration was approximate 3 minutes. The body of the triangle looked sky dark. About 5 minutes later, we noticed 3 similar sized lights to the east, only in a straight line. Not connected to a constellation, nor was it Venus, which was more to the east and brighter. I felt uneasy, we went inside.
