Filter by taxonomy in Views table
If you look at the default Taxonomy Term view provided with views, you'll see that it has a contextual filters Content: Has taxonomy term ID (with depth) and Content: Has taxonomy term ID depth modifier. Both are needed. If you look at the description for the Depth field for the first filter you'll see the following:


  The depth will match nodes tagged with terms in the hierarchy. For example, if you have the term "fruit" and a child term "apple", with a depth of 1 (or higher) then filtering for the term "fruit" will get nodes that are tagged with "apple" as well as "fruit". If negative, the reverse is true; searching for "apple" will also pick up nodes tagged with "fruit" if depth is -1 (or lower).


In your case fruit is applied and apple is, for example, Geometry. So if you specify a depth of 1 or higher you should get the behaviour you want.
