In this 12-part series, students will use coordinates on a number line to find segment lengths along with the proper use of a protractor to measure angles. They will use problem solving to find missing segment lengths and angle measures. Problems involving algebra are also incorporated into the lesson. Students will use The Ruler Postulate, The Segment Addition Postulate, The Protractor Postulate, and The Angle Addition Postulate. Part of the "Zero the Math Hero" series.
