axis noun [C] (IMAGINARY LINE) a real or imaginary straight line going through the centre of a object that is spinning, or a line that divides a symmetrical shape into two equal halves: The earth revolves around the axis that joins the North and South Poles.

(Entry 1 of 2) 1a : a straight line about which a body or a geometric figure rotates or may be supposed to rotate the Earth’s axis. b : a straight line with respect to which a body or figure is symmetrical the axis of a cone. — called also axis of symmetry.

A line, used as a reference to determine position, symmetry and rotation.

: the straight line through all fixed points of a rotating rigid body around which all other points of the body move in circles.

In reference to human anatomy, axis of rotation is an imaginary line that projects through the pivot/rotation point in a joint (for example, the axis of rotation for flexing and extending the arm projects through the elbow joint).

Also called axis of symmetry, symmetry axis of rotation.

These three axes, referred to as longitudinal, lateral and vertical, are each perpendicular to the others and intersect at the aircraft centre of gravity. Motion around the longitudinal axis, the lateral axis and the vertical axis are referred to as roll, pitch and yaw respectively.

Sagittal axis runs through the body horizontally from the left to right. Frontal axis runs through the body horizontally from the back to front. Movement in the sagittal plane about the frontal axis allows for front somersaults/forward roll. Movement in the frontal plane about the sagittal axis allows for cartwheels.

STef (Sagittal plane, Transverse axis, extension, flexion) FFaa (Frontal plane, Frontal axis, abduction, adduction) TLr (Transverse plane, longitudinal axis, rotation) – remember this as The London Railway!

There are three planes commonly used; sagittal, coronal and transverse.

A plane is the two-dimensional analogue of a point (zero dimensions), a line (one dimension) and three-dimensional space.

all three planes form a cluster of planes intersecting in one common line (a sheaf), all three planes form a prism, the three planes intersect in a single point.

Intersection of Three Planes

All three planes are parallel	Just two planes are parallel, and the 3rd plane cuts each in a line
The intersection of the three planes is a line	The intersection of the three planes is a point
Each plane cuts the other two in a line	Two Coincident Planes and the Other Intersecting Them in a Line

The intersection of two planes is a line. They cannot intersect at only one point because planes are infinite.

Properties of Intersecting Lines The intersecting lines (two or more) always meet at a single point. The intersecting lines can cross each other at any angle. This angle formed is always greater than 0∘ and less than 180∘. Two intersecting lines form a pair of vertical angles.

Intersection is denoted by the U+2229 ∩ INTERSECTION from Unicode Mathematical Operators. The symbol U+2229 ∩ was first used by Hermann Grassmann in Die Ausdehnungslehre von 1844 as general operation symbol, not specialized for intersection.

Parallel lines are equidistant lines (lines having equal distance from each other) that will never meet.

In geometry, a line can be defined as a straight one- dimensional figure that has no thickness and extends endlessly in both directions. It is often described as the shortest distance between any two points. Here, P and Q are points on the line. Fun Facts.

There are many types of lines: thick, thin, horizontal, vertical, zigzag, diagonal, curly, curved, spiral, etc.

There are 5 main types of lines in art: vertical lines, horizontal lines, diagonal lines, zigzag lines, and curved lines. Other types of lines are simply variations of the five main ones.
