Inscribed Square
Follow these steps to construct a square inscribed in a circle.
1) Using the LINE TOOL, create the diameter through B.
Click on the line tool, click on A, then click on B
2) Using the POINT TOOL create point C as the other endpoint on the diameter.
This SHOULD NOT BE a purple point, it should be a black point.
3) Using the POINT TOOL create point D somewhere between A and C.
This WILL BE a purple point.
4) Using the COMPASS TOOL, create a circle with radius BD and center point B.
Click on the compass tool, click on B, the D, then B
5) Using the COMPASS TOOL, create a circle with radius BD and center point C.
Click on the compass tool, click on B, the D, then C
6) Using the POINT TOOL label where the last two larger circles intersect as E and F.
These SHOULD NOT BE a purple points, they should be a black points.
7) Using the LINE TOOL, draw a line through points E and F.
Click on the line tool, click on E, then click on F
8) Using the POINT TOOL, label where the line intersects the circle as G (top) and H (bottom).
These SHOULD NOT BE a purple points, they should be a black points.
9) Using the SEGMENT TOOL, draw a segment from point C to point G.
Click on the Segment tool, click on C, then click on G
10) Using the SEGMENT TOOL, draw a segment from point G to point B.
Click on G, then click on B
11) Using the SEGMENT TOOL, draw a segment from point B to point H.
Click on B, then click on H
12) Using the SEGMENT TOOL, draw a segment from point H to point C.
Click on H, then click on C
RESULT: Square CGBH inscribed in circle A.
