It's a Small (Geometric) World

It's a small world! This structure is made of all kinds of different shapes, and you can find tons of concepts from Geometry in this picture. On the far left, there is a grid-like shape that demonstrates parallel lines being cut by traversals. There are lots of vertical angles, in the middle of the right side, and next to the grid on the left side. On top of the clock (in the middle), there are also two blue congruent triangles. (~CD1)
