Welcome! Read the instructions and then drag the objects shown. Press the “Take Control” button at the bottom, then select the “Move Tool” arrow at the left end of the Tool Bar near the top. Touch or click on a point in the geometry figure to drag it. Next, create your own similar geometry objects using the buttons in the Tool Bar. Create points, lines, circles and triangles. Drag them around and notice how they change. To create a triangle, use the polygon tool and click on three points to define the triangle and then click again on the first point to complete the triangle.
