The perpendicular line tool is provided. Select the line first, then the point (the instructions appear at lower left when you click on the tool). For a challenge, try to do the construction using only the circle tool. The short solution is here. |
| Now that you can construct a perpendicular, you can easily construct a parallel. It's always a good strategy to reduce new problems to problems that you've already solved. |
