Move a free point:
By default, free points are red. You click on the point and left button
pressed, you move
the point and all the figure is rebuilded .
Create a new free point
Click into disc to place this new point
Drawing a segment
Click on two points, free or not, and the segment is created.
Drawing a line
Click on two points, free or not, and the line is created.
Drawing perpendicular line through midpoint
Click on two points, free or not, or on one segment.
Drawing a perpendicular line
Click on a point, free or not, and a line or a segment to give direction.
Select order has no importance.
Drawing intersections
You can select two segments, one segment and one line, two lines, one segment
and one circle, one line and one circle or two circles. Select order has no
importance.
Drawing midpoint of two points or a segment
Click on two points, free or not, or on one segment.
Drawing circle's center
Select one circle, the point will be the center of the circle.
Drawing circle by diameter
Select two points or a segment to define diameter of the circle.
Drawing circle by center and a point
Select two points, first is the center and the circle pass through the second.
.
Drawing circle by three points
Clich on three points, free or not, the circle will passed through the
three points if they are not on a same line.
Reflecting an object through a point
You select one point as center and the object to be reflected, point, segment,
line, polygon or circle.
Reflecting an object through a line
You select one line as mirror and the object to be reflected, point, segment,
line, polygon or circle.
Buildind bisector of three points
You select three points. The order of selection determines the angle, with the second point being the vertex of the angle.
Put a point on an object
You click on a line or a circle, one point is created on this line or this
circle.You can drag the constructed point, but it always stays on the object on which it was
created.
Drawing the locus of a point or a line
Select a point on object and one constructed point or one line. If the locus
object is a point, you will have a continuous curve stitched together from sampled locations of the point as the driver point moves along its
path. Otherwise the locus will be a set of lines.
Déficit d'un triangle
You select three points. The deficit of the triangle is 180 - (total value of
angles). Area can be measured as k x deficit.
Distance between two points or length of a segment
This command displays the distance between two selected points or the length of
a selected segment.
Angle defined by three points
This command displays the measure of the angle defined by three selected points. The order of selection determines the angle, with the second point being the vertex of the angle.
