We began our focus on triangles this week in Geometry. We learned the Triangle Sum Theorem and the Exterior Angle Theorem. Both of these theorems helped us find the missing measures of angles in a triangle.
Then we moved on to a picture of intersecting lines that had 24 missing angles. Knowing the measure of just 3 of the angles, we were able to apply our knowledge of angles and laws of Geometry to find the other 21 missing angles. When we first looked at the diagram, most people thought that it was going to be next to impossible to find all of the missing angles. But, after we solved the problem together, most said that it was much easier than they thought!
Next week we will continue practicing sec. 3.3 & 3.4 and will be having a quiz on Wednesday!
