Below are six rooms, as seen from above. Your task is to place the minimum number of[br]security cameras need in each room, so that all parts of the room can be monitored. For each[br]room, mark where the camera(s) should be placed using a point.
Can you find a relationship between the number of corners (or vertices) in a room and the[br]number of cameras required? Try to use this observation to find the maximum number of[br]cameras that may be needed for a room given the number of vertices.[br][br]Hint: Try drawing rooms with different shapes.
