Drawing with selected point objects

Draw line from A perpendicular to CD

When you tap on any point of construction, the point will be highlighted by the small green circle around it and point tools will be appeared on the bottom of screen.

There many useful tools for drawing with selected points (A). To select a point touch on it or use selection tools (point option):

1) Draw line form point A to other points or new point
2) Draw straight line from point A perpendicular to arbitrary line. A picture shows how to do that.
3) Draw straight line from point A parallel to arbitrary line
4) Draw an arc of center A, with required length on any direction
5) Draw a circle with a diameter from A to any point
6) Draw a circle passing through A and tangent line
7) Draw a circle of center A and passing through any other point
8) Draw a circle passing through A and two other points


Simply drag the tool and drop it where you needed!
