Point

New point

Clicking on the drawing pad creates a new point. Its coordinates are fixed when the mouse button is released again.

By clicking on a segment, straight line or conic section you create a point on this object. Clicking on the intersection of two objects creates this intersection point.

Intersect two objects

The intersection points of two objects can be produced in two ways.

1. Mark two objects: all intersection points are created (if possible)
2. Click on an intersection of the two objects: only this single intersection point is created

For segments, rays or arcs you may specify whether you want to allow outlying intersection points (properties, 3.1.1). This can be used to get intersection points that lie on the extension of an object. For example, the extension of a segment or a ray is a straight line.

Midpoint

Clic on ...

1. two points to get their midpoint.

2. one segment to get its midpoint.

3. a conic section to get its center.
