There are several "linear" objects that we can see in a single day. A pencil, for example - or even your body when standing straight up.
"Bent" geometries are a bit harder to find. I noticed that my lamp, which has adjustable joints, can form a stick-and-ball model of a "bent" molecular geometry.
One of the most difficult to find, in my opinion, would definitely have been the "trigonal pyramidal." I noticed that a foldable stool illustrates the idea of three bonds and one lone pair quite nicely.
If you go driving, you may notice a Mercedes on the streets. This is where I found an example of the "trigonal planar" geometry. The logo itself is drawn via connecting the vertices of a triangle inscribed in a circle.
Finally, a "tetrahedrally" shaped item can be easily located by any photographer. One of their main tools, the tripod, forms this shape almost perfectly. In fact, when the tripod is un-extended, it could fall under the trigonal pyramidal category.
