Points, Lines and Planes Worksheet
- Identify which of the following sets of points are collinear: A(2, 3), B(5, 7), C(8, 11).
- Determine if the points D(4, 6), E(4, 6), and F(4, 8) lie on the same line.
- Given three non-collinear points, how many distinct lines can be drawn through them?
- Determine whether the points G(2, 3, 1), H(4, 1, 3), and I(6, 5, 2) lie on the same plane.
- Find the equation of the line passing through the points P(2, 1) and Q(4, 5) in slope-intercept form.
- Determine the distance between the points R(3, 2, 4) and S(7, 5, 8).
Points, Lines and Planes
Points, Lines, and Planes are basic terms used in Geometry that have a specific meaning and are used to define the basis of geometry. We define a point as a location in 3-D or 2-D space that is represented using the coordinates.
We define a line as a geometrical figure that is extended in both directions to infinity. Similarly, a plane is defined as the collection of all such lines, i.e. it is a 3-D space on which the line passes.
In this article, we will learn about Points, Lines, and Planes in detail including their solved examples and problems based on them.
