GeoGebra 命令及参数

1. Flatten(Sequence[Shuffle[{1, 1, 2, 2}], i, 1, 25]) → randomNumbersType
2. Element(randomNumbersType, Mod[questionCount, Length[randomNumbersType]] + 1) → randomType
3. Join({Shuffle[25…60], Shuffle[25…60]}) → randomNumbersKom
4. Join({Shuffle[25…150], Shuffle[25…150]}) → randomNumbersSup
5. If(randomType ≟ 1, Element[randomNumbersKom, Mod[questionCount, Length[randomNumbersKom]] + 1], Element[randomNumbersSup, Mod[questionCount, Length[randomNumbersSup]] + 1]) → randomAngle
6. If(randomType ≟ 1, 90 - randomAngle, 180 - randomAngle) → randomAngle2
7. Flatten(Sequence[Shuffle[{"α", "β", "γ", "δ", "ε"}], i, 1, 20]) → randomLetters
8. Element(randomLetters, Mod[questionCount, Length[randomLetters]] + 1) → randomLetter
9. Defined(input) → clickableBtnValidate
10. Textfield(input) → inputBox
11. Rotate(AngleRef, (randomAngle° * Random[1, 4]), AngleCenter) → AngleStart
12. Rotate(AngleStart, randomAngle°, AngleCenter) → AngleEnd
13. Angle(AngleStart, AngleCenter, AngleEnd) → angle
14. Segment(AngleCenter, AngleStart) → angleStartLine
15. Segment(AngleCenter, AngleEnd) → angleEndLine
16. Rotate(AngleStart, If[randomType ≟ 1, 90°, 180°], AngleCenter) → AngleHint
17. Angle(AngleStart, AngleCenter, AngleHint) → angleHint
18. Segment(AngleCenter, AngleHint) → angleHintLine
19. Angle(AngleEnd, AngleCenter, AngleHint) → angle2
