A review of angles will be completed before we begin studying triangles. We will focus on congruent triangles the triangle sum theorem. A homework assignment involving was sent by email.

We will complete our study of angles by identifying angle pairs formed by two parallel lines cut by a transversal. We will also state the theorems related to this situation. Some applications of angles to real situations will also be presented. We will end class by introducing triangles and defining appropriate terms. The assignment is to look at the 11-page handout to review each new term.

We will study the congruent supplements theorem, the congruent complements theorem, and the angle bisector theorem and its converse. We will write a definition for parallel lines.

Review the definition of angle and identify the vertex and measure of an angle. Several theorems will be presented related to angles, and we will use them to solve problems. The vertical angle theorem and the linear pair theorem are very important for applications. Homework will involve problem solving using the theorems.

We will start with definitions of complementary, supplementary, and vertical angles. We will define the term angle bisector and prove the angle bisector theorem. We will study the linear pair theorem, the congruent complements theorem and several other theorems as time permits. We will also define the concept of the converse of a theorem.

Written review assignment to prepare for FLVS Geometry Final Exam. Solving 18 practice problems covering various essential geometry topics and methods.

After the homework quiz we will prove our first theorem. The steps in a formal proof will be shown as we prove the common segments theorem with a formal statements - reasons proof. The process is the important emphasis of the proof. This will be followed by introducing the concept of an angle.

We will begin by going over the assignment from yesterday. We will the define colinear points. This will lead to a discussion of the segment addition postulate and allow us to look at situations that determine a unique plane, these include three noncolinear points, two intersecting lines, and two parallel lines. The assignment will be to look up these new concepts on the 11-page document.

We will start with a homework quiz. The new material for today will focus on lines. We will start with segments, rays, and half-lines. We will define the term between as it relates to geometry and do some problems using the definition. We will look at examples of intersecting lines, skew lines, and parallel lines,

We will discuss the syllabus, class procedures and an overview of the course content. We will study the concept of undefined terms as related to geometry (point, line, and plane). We will discuss the statement types used in formal geometry: definition, postulate, and theorem.
