In Geometry students have been using a ruler and a protractor for many years. There are 4 postulates, or ideas, about using the ruler and protractor that are understood to be true when we use them.
On the activity sheet students answer questions based on the
Ruler Postulate, the Segment Addition Postulate, the
Protractor Postulate, and the Angle Addition Postulate.
The activity sheet contains 15 questions that can be used as the basis of a lesson or for a classwork or homework sheet on using the segment and angle postulates.
A complete set of solutions are included.
