Construction - Isosceles Triangle - II

In continuation to my last post, this is the second method of construction of an isosceles triangle. This construction uses the fact that all the radii of a circle are equal. 

Following are the steps of construction : 

1. Draw a circle from with centre O. 
2. Take two points A and B on the circumference of circle. 
3. Draw line segment OA. 
4. Draw line segment OB. 
5. Draw line segment AB.
Triangle OAB is the required isosceles triangle. This is a Java Applet created using GeoGebra from - it looks like you don't have Java installed, please go to
