We now need to be able to copy and angle!

Use the tools provided in the applet to copy angle ABC onto line DE, see what you can work out on your own but if you need help, watch the video below.

In the last basic construction we learn how to bisect an angle which means we have unlocked a new tool, angle bisector[icon]/images/ggb/toolbar/mode_angularbisector.png[/icon]! Does the same thing we did in BC4, just quicker.[br][br]To use the tool, select[icon]/images/ggb/toolbar/mode_angularbisector.png[/icon], then select the vertices of the angle (ABC in this case).[br][br]Play around with the tool and get comfortable with using it.
