In Euclidean geometry, an angle is a figure consisting of two rays, called the sides of the angle, that share a point d, called the vertex of the angle.
What Is The Measurement Of Angle 1
Angles formed by two rays are also called planar angles because they lie in the plane of the rays. Agosh is also formed by joining two planes; these are called dihedral angles. Two intersecting curves can also define an angle, which is the angle of the rays subtending the tangent of the corresponding curves at the point of intersection.

The size of an angle is called the measure of the angle or simply “the angle”. The angle of rotation is a measure usually defined as the ratio of the length of a circular arc to its radius, and it can be a negative number. In the case of a geometric angle, the arc is cut at the apex and bounded by the arcs. In the case of rotation, the arc is on the line of rotation and bounded by a point other than its image with rotation.
The word angle comes from the Latin word angulus, which means “angle”. Greek cognates ἀγκύλος (ankylοs) which means “sleepy, curled up” and literally “dog”. Both are related to the Proto-Indo-European root *ank-, meaning “to cry” or “to cry”.
Euclid defines a plane angle as the inclination to each other in the plane of two lines that meet and are not perpendicular to each other. According to the Neoplatonic Metaphysician Proclus, an angle must be either qualitative, quantitative or relational. The first concept of angle as a quality was used by Rodas Eidems, who considered an angle as a deviation from a straight line; the other, angle as a quality, by Carpus of Antioch, who regarded it as the interval or space between the lines of intersection; Euclid introduced a third: angles as ratios.
, . . . ). Small Roman letters (a, b, c, . . . ) are also used. In a context where it is not complex, an angle for its apex may be indicated with a capital roman letter. See the figures in this article for examples.
History Of Contact Angle Measurement
In geometric figures, angles can also be identified by the three points that define them. For example, the angle formed by point A with rays AB and AC (i.e. the bisectors of point A through points B and C) is denoted ∠BAC or B A C ^ }}}. If there is no risk of confusion, an angle can sometimes be represented by just one vertex (“angle A” in this case).
Conceptually, an angle denoted as ∠BAC can refer to one of four angles: an angle from B to C on A, a counter-clockwise angle from B to C on A, a clockwise angle from C to B on A, or the counterclockwise angle from C to B at A, the direction in which the angle is measured specifying its sign (see § Signed Angles). However, in many geometric cases it is clear from the context that a positive angle is less than or equal to 180 degrees, and in these cases no ambiguity arises. In addition, special conventions may be adopted to avoid confusion, such as ∠BAC is always counterclockwise (positive) from B to C with respect to A and ∠CAB to A- the counterclockwise (positive) one refers to C to B.
Angles A and B are a pair of vertical angles; angles C and D are a pair of vertical angles. Hatch marks are used here to indicate angle equality.
If two lines intersect at a point, four angles are formed. These angles are named in pairs according to their position relative to each other.

A line is a line that intersects a pair of lines (often parallel) and is connected by various interior angles, corresponding angles, interior angles, and exterior angles.
The size of the geometric angle is usually defined as the smallest amount of rotation that maps one of the rays to the other. Angles that have the same measure are called congruent, congruent, or congruent.
In some cases, such as defining a point on a circle or defining the direction of an object in two dimensions relative to a reference direction, angles that differ by an exact multiple of a full rotation are effectively equivalent. In other contexts, such as defining a point on a spiral curve or describing the cumulative rotation of an object in two dimensions relative to a reference direction, angles that differ by a non-zero multiple of a full rotation.
, a circular arc is drawn at the vertex of the angle, e.g. with a pair of compasses. lgth ratio

A circle is the number of radians in an angle. Generally, in mathematics and SI, the radian is considered equal to the dimensionless value of 1.
An angle expressed in a different angle unit can be obtained by multiplying the angle by an appropriate shape conversion constant.
K / 2π, where k is the exact degree of rotation in chos (eg k = 360 degrees or 400 degrees):
The value of θ defined in this way does not depend on the size of the circle: if the lgth of the radius is changed, then the lgth of the arc changes in the same way, so the ratio s/r does not change.

The measure of angle AOC is the sum of the measures of angle AOB and angle BOC.
Throughout history, angles have been measured in different units. These are known as angular units, and the most modern units are degrees (°), radians (rad), and gradians (grad), although many others have been used throughout history.
Most angle units are defined such that one revolution (ie the angle subtended by the circumference of a circle at its center) is equal to n units for some integer n. Two exceptions are the radian (and its decimal fractions) and the nautical mile.
In the International Number System, an angle is defined as a dimensionless quantity, and in particular the unit of radii is dimensionless. This convention affects how angles are stored in dimensional analysis. See Radian § Dimensional Analysis for discussion.
Drawing And Measuring Angles
A radius is determined by the circumference of a circle, which is equal to the radius of the circle (n = 2π = 6,283…). It is the angle subtended by the length of an arc of a circle whose length is equal to the radius of the circle. The symbol for radian is rad. One rotation is 2π radians, one is radians
180° / π or about 57.2958 degrees. Often, especially in mathematical texts, one radian is treated as one, resulting in the rad unit being omitted. Radians are used in virtually all mathematical work beyond simple practical geometry, for example because of the nice and “natural” properties that trigonometric functions exhibit when their arguments are in radians. The radian is the SI unit of angle (out).
A degree represented by a small superscript circle (°) is 1/360 of a turn, so a rotation is 360°. One of the advantages of this old hexadecimal division is that many angles, common in simple geometry, can be measured in a whole number of degrees. Fractions of a degree can be written as regular decimals (eg 3.5° is three and a half degrees), but the “minute” and “second” sex divisions of the degree-minute-second system (discussed below) are also used. used mainly for geographic coordinates and in astronomy and ballistics (n = 360)
1/21, 600 turns. It is denoted by a single prime number (‘). For example, 3° 30’ equals 3 × 60 + 30 = 210 minutes or 3 +

30/60 = 3.5 degrees. A mixed tens format is also sometimes used, e.g. 3° 5.72′ = 3 +

1/3600 degrees (n = 1,296,000). It is marked with a double apostrophe (″). For example, 3° 7′ 30″ becomes 3 +
Degree, also called degree, gradian, or gon. It is the decimal division of the square. A right angle is 100 degrees. Kilometers have historically been defined as arc degrees on the Earth’s meridian, so a kilometer is the decimal analog of six hundred nautical miles (n = 400). The degree is mostly used in trigonometry and continental surveying.
