In machining, the rake angle is a parameter used in various cutting processes, describing the angle of the cutting face relative to the workpiece. There are three types of rake angles: positive, zero or neutral, and negative . Positive rake: A tool has a positive rake when the face of the cutting tool slopes away from the cutting edge at inner ...
Acute and obtuse triangles. An acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°). An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles. Since a triangle's angles must sum to 180° in Euclidean geometry, no Euclidean triangle can ...
Angle of view (photography) A camera's angle of view can be measured horizontally, vertically, or diagonally. In photography, angle of view ( AOV) [ 1] describes the angular extent of a given scene that is imaged by a camera. It is used interchangeably with the more general term field of view . It is important to distinguish the angle of view ...
Goniometer. Goniometer made by Develey le Jeune in Lausanne, late 18th–early 19th century. A goniometer is an instrument that either measures an angle or allows an object to be rotated to a precise angular position. The term goniometry derives from two Greek words, γωνία ( gōnía) ' angle ' and μέτρον ( métron) ' measure '. [ 1]
Angle. A green angle formed by two red rays on the Cartesian coordinate system. In Euclidean 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. [ 1] Angles formed by two rays are also known as plane angles as they lie in the plane that contains the rays.
Rectangle. In Euclidean plane geometry, a rectangle is a quadrilateral with four right angles. It can also be defined as: an equiangular quadrilateral, since equiangular means that all of its angles are equal (360°/4 = 90°); or a parallelogram containing a right angle. A rectangle with four sides of equal length is a square.
The sternal angle is a palpable and visible landmark in surface anatomy, presenting as either a slight body ridge or depression upon the upper chest wall which corresponds to the underlying manubriosternal joint. [ 4] The sternal angle is palpable and often visible in young people. [ 2]: 319. The sternal angle corresponds to the level of the ...
The azimuth is the angle formed between a reference direction (in this example north) and a line from the observer to a point of interest projected on the same plane as the reference direction orthogonal to the zenith. An azimuth ( / ˈæzəməθ / ⓘ; from Arabic: اَلسُّمُوت, romanized : as-sumūt, lit. 'the directions') [ 1] is the ...
