AMUSEMENT MILE - RIDDLER TROPHY #9
There are three panels nearby. Look for the first on a high rooftop just north of the caged trophy. Glide from this one into the one the wall, then make sure to press A to glide off the wall in the opposite direction so that you can tag the final panel. From there, get back to the cage as quickly as you can.

The riddler panel here alternates between green and red. Step on it when it’s green to unlock the nearby trophy cage.
AMUSEMENT MILE - RIDDLER TROPHY #14
Stand on the riddler panel. This will light up the nearby switches in a certain sequence. Memorize the sequence, then use your batarang or remote electric charge to deactivate each switch in order. This process repeats three times, each with a different pattern, so stay on the panel or everything will reset.
