Our objectives for this packet include:
-Understanding the sum of angles in a triangle
-The exterior angle theorem and how to use it
-Solving for angle measures algebraically, using these concepts
Through a powerpoint and several walkthrough videos, we will learn many properties about angles in a triangle and how to use them to solve problems.
What interior and exterior angles are (parts of a triangle), as well as an explanation of the exterior angle theorem.
Why angles of a triangle always add up to 180.
A step by step example of how to solve for angles of a triangle given algebraically, using the exterior angle theorem.
How to solve a triangle's angles when two angles are given algebraically and one is given in degree form.
A step-by-step problem of how to solve for the angles of a triangle if all three are given algebraically.
