Click on the blue points and drag them to change the figure.

Manipulative 1 - Cylinder Created with GeoGebra.

A cylinder is a solid with two circular ends (see figure 1).[1] A cylinder can be formed by rotating a rectangle around one of its sides (see figure 2). Click on the points on the sliders in figure one and drag them to change the figure. Click on the blue point in figure 2 and drag it to see a cylinder form from a rectangle.
