MATHEMATICS NOTES CHAPTER - 11

Points to Remember

Below we have provided some of the important points to remember for this chapter to ace the exams:

• A three-dimensional shape is a three-dimensional figure, object, or shape with three dimensions: length, width, and height.

• Skew lines are two lines that do not intersect and are not parallel in three dimensions.

• Four points chosen randomly within a unit cube will almost certainly define a pair of skew lines.

• A line segment’s projection is formed by projecting or pasting the endpoints of the existing line segment onto the new line to form a 2-D figure.

• Any two intersecting lines must be coplanar if they are in the same plane.
