Cis forCylinder

A cylinder is a long, thin shape where the ends are circles. Any cross-section of a cylinder at right angles to its outer surface is also a circle. Long cylinders are also known as tubes. Pipes are also cylinders. The cylinder you see the most often is, of course, the cardboard tube at the centre of a roll of toilet paper.

Dis forDiamond (shape)

A diamond, or rhombus is a four-sided shape, like a square turned on its side. All four sides of a rhombus are the same length but the angles on the corners do not have to be 90 degrees like in a square, the rhombus can be taller than it is wide or wider than it is tall. The window in the picture is diamond-shaped. A diamond is also a kind of precious stone.
