The term is used to describe many geometric objects such as the ones below.
|Acute triangle||Obtuse Triangle|
|Each angle has a measure less than 90°.||An obtuse triangle contains one angle greater than 90°.|
Like the oblique prism, the sides of an oblique cylinder are not perpendicular to its circular bases.
As an example, draw a cube on a piece of paper, as shown below. First, a square face is drawn as it would look head-on. Then, four parallel line segments are drawn at 45° from each vertex of the square, forming the other faces of the cube, and giving it a 3D view.
