About Geometry Worksheet Assignment 10.9:                 

 

Assignment 10.9 is an introduction to calculating measures of arcs on a circle.

 

Prerequisite Skills:  Identify and name arcs and major arcs (Assignment 10.7).  Solve algebraic equations with one variable.

 

Theorems:  The measure of a minor arc is less than 180.

                           The measure of a major arc is greater than 180.  

                           The measure of a semi-circle is 180.

                           In a circle, arcs intercepted by congruent chords have the same measure.
