Example: Copy segment [color=#0000ff]AB[/color] onto the ray provided using the compass [icon]/images/ggb/toolbar/mode_compasses.png[/icon] tool. Leave all your construction marks, but change the color of your final answer so that it stands out. At the end, measure [icon]/images/ggb/toolbar/mode_distance.png[/icon]the original segment and the copy to make sure they are the same length.

Same directions, just do it yourself this time: Copy segment [color=#0000ff]AB[/color] onto the ray provided. Leave all your construction marks, but change the color of your final answer so that it stands out. At the end, measure the original segment and the copy to make sure they are the same length.

Next, copy [math]\angle[/math][color=#0000ff]ABC [/color]onto the segment provided. Leave all your construction marks, but change the color of your final answer so that it stands out. At the end, measure [icon]/images/ggb/toolbar/mode_angle.png[/icon]the original angle and the copy to make sure they are congruent.

Next, construct the perpendicular bisector of segment [color=#0000ff]AB[/color]. Leave all your construction marks, but change the color of your final answer so that it stands out. Use the segment measurement tool [icon]/images/ggb/toolbar/mode_distance.png[/icon]and the angle measurement tool [icon]/images/ggb/toolbar/mode_angle.png[/icon]to check your work.

Finally, try out the built-in Geogebra perpendicular bisector tool [icon]/images/ggb/toolbar/mode_linebisector.png[/icon]and see how it saves time. To use it, click on the tool, then select the segment that you want to bisect. You can use the intersect and point tools to create the additional points you need in order to check your answers at the end.
