Geometry courses

"Geometry" is a high school course (typically ages 14-18); it has more advanced topics than the latter.
"Basic geometry & measurement" is a primary school course (typically ages 14 and younger); it has more basic topics than the former.

If you want to know specifically which topics are covered in each, you can look at the titles of the Units in each course, or even the titles of the videos & articles.
