使用量角器测量角度 by BCPS Math Department

GeoGebra 命令及参数

1. Point(Circle[A_1, 5]) → B_1
2. Polygon(A_1, B_1, C_1, D, E, F, B_1, A_1) → poly1, a, b, c, d, e, f, b_1, a_1
3. Sequence(((6 * cos(θ°)), (6 * sin(θ°))), θ, 0, 359) → list1
4. Point(list1) → A
5. Point(list1) → C
6. Angle(A, (0, 0), C) → α
7. Segment((0, 0), A) → g
8. Segment((0, 0), C) → h
9. Textfield(β) → InputBox1
