10/3/2007 Applied Geometry-Angle Relationships in Triangles

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 demonstrations and step by step solutions can be found here.

Homework:
page 227-230, #'s 16-23, 29-34 & 41-43
