| Construction Algorithm | ||
| 1 |  |
Construct a line AB as a given base of the square. |
| 2 | |
Construct the perpendicular line at B. |
| 3 | |
Construct a circle centered at B and has a radius AB. |
| 4 | |
Generate the intersection point C between the circle and the perpendicular at B. |
| 5 | |
Construct the line that joins between A and C. |
| 6 | |
Construct the midpoint M between A and C. |
| 7 | |
Construct the line that joins between M and B. |
| 8 | |
Construct a circle centered at M and has MB as a radius. |
| 9 | |
Join up the four points A, B, C and D to get the required square. |
