Geometry is, along with arithmetic, one of the oldest branches of mathematics. A mathematician who works in the field of geometry is called a geometer.
Essential stuff for describing the world around you. 1. Lines and angles. 2. Related angles. What about angles bigger than 360 degrees? 3. Triangles. See if it's really true, and then prove it! They have two equal sides, but what about their angles? In triangles, sides and their opposite angles are related! 4. Triangle congruence and similarity.
Geometry is all about shapes and their properties. If you like playing with objects, or like drawing, then geometry is for you!
