Three orange perfectly symmetrical triangle formation lights

My significant other and I had just parked and got out of the car to head into a grocery store to get things for dinner. It was dusk and as we started walking towards the entrance she pointed up and goes "Look at those lights". There were 3 orange lights in the sky unblinking sitting in the sky in a triangle formation. At first I thought it was those Chinese lamps that people release but quicky realized they were far too high up to be those and the perfect triangle was too odd for those. The lights were probably 15 thousand maybe 20 feet up in the sky with at least 200 yards if not more between each light and we're unmoving. I noticed a plane (probably commercial seeing as we aren't far from Jacksonville International Airport) was flying somewhat below the left bottom point of the triangle. Quickly one disappeared then another and by the time we knew it all the lights simply were gone. Sadly my phone was charging at home and hers couldn't snap a clear picture.
