Bisecting an Angle
Basic Construction 4
Now we need to learn some of the same constructions we just did but with angles instead of lines, we will start with bisecting an angle; so cutting an angle in half.
Tool Practice
This construction is not obvious but if you play around with the tools we have gained you can figure out a way to do it; there are actually multiple ways!
See if you can come up with a path on your own and if you need help, watch the video.
Tool Practice
In BC 3, we learned a new feature that we gained a tool for! We learned how to draw a perpendicular through a point so we gained the tool. Use the applet below to draw a perpendicular to AB through point C. Use the , click on the line, a then click point C.
