Instructions
| 1. |  | Select the Polygon tool and construct a triangle. Label the vertices F, G, and H. |
| 2. |  | Construct the midpoints on segments FG, FH, and GH. |
| 3. |  | Select the Perpendicular Line tool and construct a line perpendicular to the line segment FG and through the midpoint on the same line segment. |
| 4. | | Select the Perpendicular Line tool and construct a line perpendicular to the line segment FH and through the midpoint on the same line segment. |
| 5. | | Select the Perpendicular Line tool and construct a line perpendicular to the line segment GH and through the midpoint on the same line segment. |
| 6. | 
| Create and label point A from the intersection of the three lines created. |
| 7. | 
| Activate the Circle tool and construct a circle with the center at point A and through point F. |
