A dynamic geometry application written that allows creation of geometric shapes and transforms (rotation, symmetry) Euclide is a dynamic geometry creation application written in Java.
Euclide allows creation of geometric shapes and transforms (rotation, symmetry...), which depend each other. Moving a shape will also move shapes dependent on it.
In Euclide you start by placing some free points, then you create objects using these points: lines, circles, line segment, circle arcs... each new figure can in turn be used to compose new shapes.
Here are some key features of "Euclide":
Creation of shapes
Various shapes can be created from selecting other geometrical objects (shapes, measures, transforms), or by specifying manually value for position, radius... When a shape need a new point, the user clic on a point of the figure, or on the location of a new free point, which will be created in the same time as the new shape. Here is a list of available shapes:
Points:
Free point
Intersection point of a curve and a line
Point on a curve (closest point to another point)
Point on a curve (with a defined geodesic position)
Centroid of several point
Transformed point (by any planar transform)
Linear objects:
Line segments (from 2 points)
Straight lines: From 2 points, Parallel to a line through a point, Orthogonal to a line through a point, Median of 2 points, Radical axis of 2 circle
Line arcs (from 2 points, bisectors, reflexion of a ray on a curve...)
Polyline (from a series of points)
Circles
From center and a point belonging to the circle
From center and radius (given as distance measure)
From 2 diameter points
From 3 points on the circle
Circle Arcs
Circle arc from 3 points
Circle arc from 3 points, with specific orientation
Curves
Bezier curve from 4 points
Composition of several curves
Measures on shapes
Distance/length measure
Closest distance of a point to a shape
Radius of a circle
Signed distance measure
Angle measure
Signed angle between 3 points
Horizontal angle of a line or a linear object
Horizontal angle of 2 points
Counting measures
Transforms
Translation by the vector joining 2 points
Rotation around a point with a given angle
Line symetry
Point symetry
Circle inversion
