Construction Algorithm |
1 |
|
Construct
a line AB as a given base of the parallelogram. |
2 |
|
Construct
a point C above the line AB. |
3 |
|
The
translation button is already generated in the construction area. |
4 |
|
Select
the line AB and the two points A and B then press the
translation button [B to C] to construct the image of the line AB by
the defined translation. |
5 |
|
Join
up the four points A, B, C and D to get the required parallelogram. |
6 |
|
Switch
to drag mode. Pick a free element. Move it around to check your
construction. |
Construction Theorems
|
If two sides of a
quadrilateral are parallel and equal in length, then the quadrilateral
is a parallelogram.
Translation preserves the distance between points.
