Frequently Asked Questions
Three Dimensional Geometry studies the position of points in space using three mutually perpendicular axes.
It involves three independent measurements represented by \(x\), \(y\), and \(z\).
It is a reference framework consisting of three perpendicular axes intersecting at a common point.
The axes are the \(x\)-axis, \(y\)-axis, and \(z\)-axis.
The origin is the point where all three axes intersect and has coordinates \((0,0,0)\).
An ordered triplet \((x,y,z)\) represents the coordinates of a point in three dimensional space.
It represents the perpendicular distance of the point from the \(yz\)-plane.
It represents the perpendicular distance of the point from the \(xz\)-plane.
It represents the perpendicular distance of the point from the \(xy\)-plane.
The three coordinate planes are the \(xy\)-plane, \(yz\)-plane, and \(zx\)-plane.
The equation of the \(xy\)-plane is \(z = 0\).
The equation of the \(yz\)-plane is \(x = 0\).
The equation of the \(zx\)-plane is \(y = 0\).
The distance is \(\sqrt{(x_2-x_1)^2+(y_2-y_1)^2+(z_2-z_1)^2}\).
It is derived using the Pythagorean theorem extended to three dimensions.
