Unit 4, Lesson 6

Use varied protractors to distinguish angle measure from length measurement

EngageNY 60 min(s)Support for English Language Learners

In this lesson, students divide two differently shaped circles into fourths and compare the angles and arc lengths that are created. Students discover that equal angles do not necessarily result in equal arc lengths. Finally, students use circular and 180 degree protractors to verify their discovery that equal angles do not necessarily result in equal arcs.
