Plane geometry: constructing a diagram

Drawing (or constructing ) illustrations is one of the basic skills to learn and solve geometric problems. Usually when the diagram has been correctly and clearly constructed, you have completed more than half of the problem. 

Students are often asked to solve more problems but rarely practice the very basic skills without which it is very difficult to be able to draw well. The basic skills include:

- What is a good geometry diagram?
- Identify a point on the plane
- Draw a straight line on the plane
- Constructing a line
- Constructing a triangle
- Constructing a circle
- Construction of other geometric
- The basic principles to be followed


In this series I will present my experience addressing the above issues, and use the application "Plane Geometry Drawer" to illustrate. 

The version 1.1 is now available on Apple AppStore with FREE basic version and In-App Purchase to enable PRO version. Click here to download Plane Geometry Drawer for iPhone 

All comments are welcome and will be absorbed for further study.
