Reflection - maths geometry

This week I learned how to draw cubes, polygons and circles on sketchup and I tried doing some in my book. I learned how to name the face, vertice, edge and corner of a polyhedron.

Because of this learning I can now draw polyhedrons on sketchup.

Something I do not understand is how to draw them in my book because I always get the shapes mixed up and I am not sure how to count the sides.

My next steps in this learning are to learn the names of the shapes and draw them in my book properly and also I would like to learn how to draw more shapes using sketchup.
