Verification by single/multiple occurences, numerical checks
- Zoltán Kovács
In general diagonals of a parallelogram bisect each other.
You can change the position of points A, B and C. Then D will be always automatically constructed.
- Drag points A, B and C to check whether diagonal BD indeed bisects diagonal AC.
- Are segments AE and CE always exactly the same? Change precision in Options > Rounding > 10 Decimal Places, then 15 Decimal Places. Explain the situation.
