a. Create a "reference line" EF below the segments.[br]b. Create a circle with radius length AB.[br]c. Place the center of this circle at E.[br]d. Label the intersection of this circle and the line as G.[br]e. Create a circle with radius length CD.[br]f. Place this circle at [b]either[/b] E or G.[br]g. Label the intersection of this circle and the line as H.[br]h. Create a segment that has a measure of [math]AB-CD[/math].[br]i. Change the color/thickness of your newly constructed segment.[br]j. Use the distance tool to verify your construction's accuracy.
Why does your new segment represent the difference of AB and CD? How did you verify that this measurement was accurate?
