We began today with a worksheet reviewing Friday's lesson. We went over the homework that was due for today together and then moved onto our new lesson. Today's focus is on the Triangle Sum Theorem, which states that the interior angles of a triangle add up to be 180 degrees. Our objectives are:
1) Give the Triangle Sum Theorem
2) Give the Third Angle theorem
3) Give the Exterior Angle Theorem
4) Find the measures of interior and exterior angles in a triangle
We completed a worksheet in class for practice, then students worked on our graded assignment. Video demonstartions and step by step solutions can be found here.
Homework:
