说明
Be a geometer with Dr. Geo: construct and manipulate interactive sketches.
Dr. Geo is an interactive geometry application. It allows one to create a geometric sketch and to manipulate it according to its constraints. It is usable at home or at school, in primary or secondary education level.

With Dr. Geo you can construct:
可以构造:
- free point, mobile point on line, intersection point.(自由点、直线上的约束点、交点)
- line, ray, segment, vector, circle, arc, polygon, locus (直线、射线、线段,向量,圆,圆弧,多边形,轨迹)
- parallel and perpendicular line. (平行线和垂线)
- transform geometric objects by symmetry, reflection, translation, homothety. (几何变换:对称,反射,平移...)
- calculate angle, length, distance. (度量角度、长度、距离)
- teach Dr. Geo macro-construction. (宏结构)

This free version comes without the perpendicular, parallel and circle tools (免费版本不提供平行线、垂线和圆... )
