| Construction Algorithm | ||
| 1 |  |
Construct a line AB as a given base of the rhombus. |
| 2 |  |
Construct a line BC so that AB = BC considering that C is the third vertex of the rhombus. |
| 3 | |
Construct the diagonal AC. |
| 4 |  |
Switch to Mirror Mode. Define a reflection at the diagonal AC, then construct the image of the point B by reflection on AC to get the fourth vertex D. |
| 5 |  |
Join up the four points to get the required rhombus. |
| 6 |  |
Switch to drag mode. Pick a free element. Move it around to check your construction. |
| Construction Theorems | ||
| A rhombus is a parallelogram
in which two adjacent sides are equal in length and the diagonals are
perpendicular to each other. Reflection preserves the distance between points. |
