geodesic dome

A geodesic dome is a special type of dome that is made up of a lot of triangles. The triangles are arranged so that each one is connected to at least two other triangles. This special type of dome is really strong and good at spreading out weight so it doesn't crumble or collapse easily. It's like a three-dimensional puzzle that fits together perfectly and can be built in almost any shape or size.
