About Geometry Worksheet Assignment 10.8:                 

 

Assignment 10.8 is an introduction to the degree measure of arcs.

 

Prerequisite Skills:  Name central angles and their intercepted arcs (Assignment 10.6).  Measure angles with a protractor (Assignment 2.5).

 

Definitions:  The measure of an arc is the measure of the central angle that intercepts the arc.

 

                           The measure of a major arc is the measure of its central angle subtracted from 360.
