Constructing Circles

Use the above toolbar to create a circle by using different ways. Like if you want to form a circle with a center and radius, just click the first way “circle 2 points” then

1. Click on a point on the screen that will be treated as its center.
2. Click on the other point and its distance from the previous point will be considered as radius. Note: Follow the instructions on the status bar for construction of circle geometry.

For example you can create a circle with a radius controlled by a slider using the steps shown below.

Here initially a widget ‘a’ is created that controls the radius of the circle. Just put the value a when the radius of the circle is required.
