a. Create a circle with radius length AB. [br]b. Place the center of this circle at B.[br]c. Create a circle with radius length AC.[br]d. Place the center of this circle at C.[br]e. Label the intersection of these circles as D.[br]f. Draw a segment to create [math]\angle CBD[/math] such that it is [b]adjacent[/b] and [b]congruent[/b] [b]to [/b][math]\angle ABC[/math].[br]g. Use the [u]angle measure tool[/u] to verify your construction.[br]
Why is D, the intersection of the circles, the location needed to create an angle that is congruent to the first?
