[size=85][b]Step 1: [/b]Use the CIRCLE TOOL [icon]/images/ggb/toolbar/mode_circle2.png[/icon] to construct a circle with center A that intersects both sides of the angle.[br][b]Step 2:[/b] Use the COMPASS TOOL [icon]/images/ggb/toolbar/mode_compasses.png[/icon] to duplicate this circle and place it at center D.[br][b]Step 3: [/b]Use the INTERSECTION TOOL [icon]/images/ggb/toolbar/mode_intersect.png[/icon] to mark both intersections of the first circle and angle A, these will be labeled K and L. Then mark the intersection of line D and circle D. This will be labeled M.[br][b]Step 4:[/b] Use the COMPASS TOOL [icon]/images/ggb/toolbar/mode_compasses.png[/icon] to create a circle with radius KL (click on K, then L) then place this circle on center M.[br][br][i]In Step 4, you are "measuring" the opening of the angle and duplicating it on your new angle.[/i][br][br][b]Step 5:[/b] Use the INTERSECTION TOOL [icon]/images/ggb/toolbar/mode_intersect.png[/icon] to mark the intersection of circle D and circle M. This will be labeled N.[br][b]Step 6:[/b] Use the RAY TOOL [icon]/images/ggb/toolbar/mode_ray.png[/icon] to create a ray from point D to point N.[br][br]If you did it correctly, a “Nailed it!” should pop up letting you know you did it right![br][br][i]Angle D is [b]congruent [/b]to angle A.[/i][br][br]After you complete the example, work on the practice. These will not let you know if you've done them correctly. I will be checking on my computer.[/size]
