The
circumcenter is defined as the intersection of the perpendicular
bisectors of all three sides of the triangle. To find it, proceed as
follows:
- Make fixed circles around each point. Each
time you create a fixed circle, the dialog box comes up. Put the same
number in the Radius field for each circle (for instance, I chose 5).
- Each
pair of
circle intersects in two points. Draw a line through these two points.
Do this for every pair of circles (you should draw three lines).
- The intersection of the three lines should be U.
- Click the Fixed Circle tool. Make U the center, and click somewhere near A.
- In the “Edit Circle” dialog box, select “Set Size…” The dialog disappears.
- Click on U and then click on A.
- The “Well Done!” screen should appear.
This ends the tutorial for fixed circles. |
