In this example, you're going to konstuere a rhombus, but the principle around sliders can be used in many other contexts.
Definition af a rhombus:
- A rhombus is a parallelogram, where all four sides are the same Længde.
- A diamond is kendetegnet by, that the opposite angles are equal.
- The diagonals are perpendicular to each other.
Instructions:
- Press -button in the Tools Menu.
- Then press the drawing pad.
- Now comes the following menu.
- Here you can adjust the interval to shoot a.
- Change my. to 0 and max to 10.
- Shoot a is the side length. You can change the name to “Side length”.
- The menu should now look like this:
- Nu skal vi konstruere sidelængden i romben. Det gøres ved at bruge værktøjet “Segment with given length” using. -button.
- Press -button.
- Press the drawing pad.
- Write “Side length” as length:
- Press “Apply”.
- You have now constructed segment AB.
- Press -button. (shortcut Escape)
- Pull “circle” the slider “Side length” and see, what happens to the line segment AB.
- Now you need to construct a new shoot
- Press -button in the Tools Menu.
- Then press the drawing pad.
- Now comes the following menu:
- Choose “Angle”.
- Change the name to “Angle”
- Change max to 90 degrees.
- The menu for the slider should look like this:
- Press “Apply”.
- Nu skal du konstruere vinklen vha. -button.
- Press -button.
- Press B scores.
- Press point A.
- Now there is a menu.
- Write “Angle” named (Erasable the 45 degrees)
- Now the menu would look like this:
- Press “OK”.
- Press -button. (shortcut Escape)
- Pull “circle” the slider “Angle” and see, what happens to the angle.
- Choose -tool.
- Tryk på A og derefter B’. (Læg mærke til at der står B’. Pronounced “B brand”)
- The drawing should look. like this right now:
- Now you need to construct the past 2 sides of the diamond.
- Press “Parallel linje” -button.
- Tryk på linjen AB’.
- Press point B.
- Tryk AB på linjen.
- Press point B '.
- Tryk på værktøjet “Skæringer mellem 2 objekter”-button.
- Tryk på de 2 NYE parallelle linjer.
- Now the point C is constructed.
- Press -button. (shortcut Escape)
- Algebra I-VINDUET du kan nu will de 2 NYE linjer c og d:
- Tryk på de 2 Blå cirkler, SA de bliver hvide.
- Nu er linjerne skjult.
- Konstruer sidste sider vha. tool “Segment with given length” using. -button.
- Tegningen happy to be Sadan and nu skulle:
- Nu evidence at trække i skyderne “Angle” and “Side length”.
