We finished the notes on the notebook file from Thursday.

1. We proved the** Isosceles Triangle Theorem**. (4.6 in your book) This is a shortcut name that you can use. You can also write this theorem by saying, “base angles of an isosceles triangle are congruent.”

2. Theorem 4.7 in your book is the **converse** of Theorem 4.6. It says that: If two angles of a triangle are congruent, then the sides opposite those angles are congruent. We proved this theorem.

3. There are two corollaries that follow: there are in your notes. Learn them. If a triangle is equilateral, then it is also equiangular. Each angle in an equilateral triangle has a measure of 60 degrees.

4. Complete the study guide 4.6 HW in the book p. 224-225 as listed in notebook file.
