Instructions
| 1. |  | Select the Line tool and create an arbitrary line AB by clicking twice in the Graphics View. |
| 2. |  | Create a line BC. Hint: Select point B and then click in the Graphics View in order to create point C. |
| 3. |  | Activate the Parallel Line tool and create a parallel line to line AB through point C. Hint: Select the line AB and then point C. |
| 4. |  | Create a parallel line to line BC through point A. |
| 5. |  | Select the Intersect tool and create the intersection point D of the two lines. Hint: Click directly on the intersection point. |
| 6. |  | Activate the Polygon tool and create the parallelogram ABCD by successively selecting all the vertices. Note: In order to close your polygon, select the first point again. |
| 7. |  | Select the Move tool and drag the vertices of the parallelogram to check if it was constructed correctly. |
