inclination (mathematics). The inclination of a line in a plane is the angle made with the positive x axis. The inclination of a line in space with respect to a plane is the smaller angle the line makes with its orthogonal projection in the plane.

- By Deb Russell. Definition: Angles are formed by two rays that begin at the same point or share the same endpoint. The angle measures the amount of turn between the two arms and is usually measured in degrees or radians. Where the two rays intersect (come together to meet) is called the vertex.

Angle An angle can be identified in two ways. The angle symbol, followed by three points that define the angle, with the middle letter being the vertex, and the other two on the legs. So in the figure above the angle would be ∠ABC or ∠CBA. So long as the vertex is the middle letter, the order is not important.

Angles And the two straight sides are called arms. The angle is the amount of turn between each arm. There are two main ways to label angles: 1. give the angle a name, usually a lower-case letter like a or b, or sometimes a Greek letter like α (alpha) or θ (theta) 2. or by the three letters on the shape that define the angle, with the middle letter being where the angle actually is (its vertex). Example angle a is BAC, and angle θ is BCD.

inclination Inclination is defined as a tendency towards something, such as a behavior or a habit. An example of an inclination is the tendency a mother has to protect a child. 1  the act of bending, leaning, or sloping; esp., a bowing or nodding.  an inclined surface or plane; slope; incline; slant.

- 1 An angle is defined by its measure and is not dependent upon the lengths of the sides of the angle (e.g. all right angles are equal in measure). 2  Two angles which share terminal sides, but differ in size by an integer multiple of a turn, are called coterminal angles.

- Definition: A pair of non-adjacent angles formed by the intersection of two straight lines. Try this Drag an orange dot. Note the behavior of the vertical angles ∠JQM and ∠LQK. As can be seen from the figure above, when two lines intersect, four angles are formed.

What Is Angle? If O is the vertex of an angle while A and B are points on the two sides, the angle may be referred to as ∠AOB or ∠BOA (and this for any selection of the two points A and B.) In elementary geometry, the definition mostly works, altough at times a text author is forced to make excuses or skip over important details.

Angles, and More Lines Angles are also formed when a transversal intersects a pair of lines, which are not necessarily parallel. A prototypical example would be the not equal symbol: . Angles which are in the same relative position but on the other line are called corresponding angles (angles 1 and 5 in the figure below right). The word alternate is often used to indicate things on opposite sides, like some leaves on a stem. In this context it means on opposite sides of the transversal.

angle (āng'gəl) A geometric figure formed by two lines that begin at a common point or by two planes that begin at a common line. The space between such lines or planes, measured in degrees. See also acute angle, obtuse angle, right angle.

What Are Adjacent Angles? - Definition & Examples Adjacent angles are two angles that have a common vertex and a common side. The vertex of an angle is the endpoint of the rays that form the sides of the angle. When we say common vertex and common side, we mean that the vertex point and the side are shared by the two angles. Here's an example of adjacent angles: In this diagram, point A is the vertex of all of the angles shown.

Book I Definition 8. A plane angle is the inclination to one another of two lines in a plane which meet one another and do not lie in a straight line. Definition 9. And when the lines containing the angle are straight, the angle is called rectilinear.Definition 10.When a straight line standing on a straight line makes the adjacent angles equal to one another, each of the equal angles is right, and the straight line standing on the other is called a perpendicular to that on which it stands. Definition 11. An obtuse angle is an angle greater than a right angle.efinition 8.

What is an Angle Iron? An angle iron is a flat metal rod that has been folded to a 90-degree angle along its length, resulting in an L-shaped piece. Usually the two sides of the angle are of equal length. Heavier angle iron is often a structural element in buildings, bridges, and so on, while a lighter version is used for a variety of supports. An adjustable bed frame, for example, is made of this material.

What You Need to Know About Angles for Basic Maths Tests Defining angles. When someone says an angle is a certain number of degrees, they’re trying to tell you how sharp the corner is. A small angle means the corner is very sharp, while an angle of 180 degrees isn’t much of an angle at all but instead is a straight line.

Angles and angle terms A right angle is an angle measuring 90 degrees. Two lines or line segments that meet at a right angle are said to be perpendicular. Note that any two right angles are supplementary angles (a right angle is its own angle supplement). Example: The following angles are both right angles.

- Freebase (0.00 / 0 votes) Rate this definition: Angle. In geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles are usually presumed to be in a Euclidean plane or in the Euclidean space, but are also defined in non-Euclidean geometries.

Right angle For other uses, see Right angle (disambiguation). A right angle is equal to 90 degrees. A line segment (AB) drawn so that it forms right angles with a line (CD). In geometry and trigonometry, a right angle is an angle that bisects the angle formed by two adjacent parts of a straight line. More precisely, if a ray is placed so that its endpoint is on a line and the adjacent angles are equal, then they are right angles.

- Definition: An angle whose measure is exactly 90°. Try this Adjust the angle below by dragging an orange dot and see how the angle ∠ ABC behaves. Note that it is a right angle only when its measure is exactly 90°. Right angles are one of the most common and interesting angles in all of geometry.It even has its own angle symbol. In the figure above, set the angle to 90° and see that instead of a small arc, the angle is marked with a small square symbol.If you see this, the angle measure in degrees is usually omitted.Note also that right triangles are those where one interior angle is a right angle.t even has its own angle symbol.
