Lesson 1-1 - Getting Started

Welcome to Honors Geometry and your class notes!  Today, we got ourselves going by looking at the three "Building Blocks of Geometry" that the crazy Greeks (Plato, Pythagoras, Euclid, et. al.) came up with some 3,000 years ago.  These are points, lines, and planes:

Definition of a Point

Definition of a Line


Definition of a Plane


We discussed the fact that all of Euclidean geometry (that which we'll be studying this year) is derived from these three building blocks.  From there, we started to develop our database of geometric terms, starting with a segment.

Definition of a Line Segment

We then defined rays and angles.  Make sure that you get down the symbology (how we write them symbollically) of these as well as the definitions!

Defnition of a Ray


Definition of an Angle


We then talked about the union and the intersection of various geometric figures.  Make sure that you can do problems that incorporate these concepts!
