GEOMETRY:
Geometry: It's an area of knowdedge wich studies any elements and operations.
Point: In geometry a point can be defined as the place or location where two lines intersect. A point has not dimensions, no height and no width.
Line: A one dimensional object formed of infinite points.It has not end points and continues on forever in a plane.
Ray: A line wich beggins at a particular point and extends and lessly in one direction.
Freehand: Draw by hand without guiding instruments and measurements.
Line/Technical drawing: It is a drawing made whit the help of suppliers.
Midpoint: It is the point that is halfway between the endpoint of the line segment.
End point: And end point is a point at which a line segment or a ray ends or starts.
Line segment: It is a line with two endpoints.
Length: Measurement of something from end to end.
Compass: It is a tool for drawing circles and arcs and also for measuring between points.
Protractor: Is an instrument for measuring or drawing angles on paper.
Set squares (UK) triangles (US): There are two special rulers.One is called the 45 triangle and other 60/30 triangle.
Eraser: Use for eliminate the mistake.
Ruler: For making lines.
Line segment copying: Given the segment AB, copy it with the same length with a compass.
Circles: Set of points at the same distance to a point called center.
Radius: It is a length of a line segment from the center to its perimeter (radiuses-plural).
Diameter: A line segment that passes through the center and conects two points of a circle.Its length is double than the radius.
Circunference: It is the full length of a circle.
Chord: A line segment which conects two points of the circle not though the centre.
Arc: Segment of a circle.
Centre: It is a point equidistant to any points on a circle.
Arrow: It is a line segment enter chord and arc pass to the centre.
IMPORTANT DEFINITIONS ABOUT ANGLES AND LINES:
Parallels: They are two lines which never intersect themselves.So all their points are equidistant.
Perpendicular: They are lines which meet forming four right angles-90.
Oblique: They are lines which are not parallels neither perpendicular.
Angles: It is a figure formed by two rays sharing a common enpoint.
TYPES OF ANGLES:
Complementary angles: They are couples of angles which sum is 90.
Suplementary angles: They are couples of angles which sum is 180.
POLYGONS:
Star polygon: It is a particular polygon case with a star and is consecutive vertices of a regular polygon.
Inscribed polygon: They are polygons place inside circles so all the vertex of the polygon.
Convex polygon: Any line draw through the polygon meets its boundary exactly twice.
Non convex (concave): A line may be found which meets its boundary more than twice.
Triangles: It is a flat figure with three sides and three angles.
Quadrilaterals: They are polygons with four sides and four angles.
Parallelograms: They are quadrilaterals with two sides of parallels opposite equal sides and two pairs opposite equal angles.
IMPORTANT DEFINITIONS RELATED TO SYMETRY:
Symmetry: It is a quality of some shapes which some of their parts are reflections of others.
Reflection symmetry: It is a shape quality which is formed by two halves facing each other with an axis or fold line in between as if bath side were mirror images of each other.
Symmetry Axis: It is a line which divedess a shape into two symmetry halves. Every elements are the same distance from the axis.
Vocabulary:
Dot: It is a smallest and most simple element in art expression.
Three-dimensional capacity: When the size,shapes and colors and changed.
Expensive capacity: The point has a unlimited capacity to represent images and to express ideas and emotions.
Optical mix: When colorsb are mixed with the help of distance point aren't mixed on the palette or on the points.
DOT GEOMETRY:
Dot: It is a smallest and most simple element in art expression.
Three-dimensional capacity: When the size, shapes and colors are changed and create a visual sensations.
Exprensive capacity: The point has a unlimited capacity and create a unusual efect.
Optical mix: When colors are mixed with the help distance , it is used by pointillist.
LINES:
Way line: They are formed by several fragments of curved lines.
Curly line: They hold more curves than way lines and show loops.
Scribble: It is a line that are traced randomly usually in first stages.
Hatching: It's a way of shading or giving tomes to the areas of objects.
Cross hatching: It's a way of shading areas of a drawing.
Dashed lines: They are lines which are not continius.
Blured: They are very soft so they are hard .
Composite lines: They are lines composed by fragments.
Vertical lines expressiveness: The express an ascendent or descendent movement.
Horizontal lines expresiveness: They produced of stability and calmess or tranquility.
Skew lines expresiveness: They produced movement feelings.
DEFINITIONS ABOUT THE PLANE OR FLAT SHAPE:
Plane: It could be a spot or a brushtroke. It is a two-dimensional surface, height and width but not depth.
The plane three dimensional capacity: It is consists on creating volume when several flat shapes get together.
Flat organic shapes: They follow natural principles and can take countles appareances.
Flat geometric shapes: They follow mathematical principles. In unusual arts there are: circle, square and triangle.
DEFINITIONS ABOUT TEXTURE:
Texture: It is the unusual and tactile quality of the surface due to the material.
Tactile textures: Are those that can be percived through the sers of touch.
Natural texture: Those that can be found in nature.
Artificial texture: Are those created by the human being macanically.
Rubbing tecnlogye: It consists on fructionary or publing a crayon or colored.
Scratchboarding: It is usually done with maxed colors. When scratching over the first .
IMPORTANT DEFINITIONS ABOUT COLOR:
Color: It is a basic element of visual language. It is a light impression that arrives to the eyes.
Primary: red, green and blue V.
Secondary: yellow, cian and magent.
Pigments: It is a powder that you use to do or make all the things that have color.
Primary: magent, cian and yellow.
Secondary: blue V, red and green.
THE THREE PROPERTIES OF COLOR:
Hue: Also called Tone or tint, it is the name of the color defined by its wavelength.
Saturation: Degree of purity of a color. If a color is very saturated it means that it is very pure and doesn't have many colors in its mix.
Value: Sometimes called brightness or luminosity. It is the amount of black or white that a color has in its mix.
Complementary colors: They are pairs of colors which are located one in front of each other on the color wheel. Is formed by the mix of other two primary in equal parts.
Warm range: It's a scale of colors that has either more yellow, more magent, or both in this mixture. They express warmth, energy, youthness or proximity.
Reflection symmetry: It is a shape quality which is formed by two halves facing each other with an axis or fold line in between as if bath side were mirror images of each other.
Symmetry Axis: It is a line which divedess a shape into two symmetry halves. Every elements are the same distance from the axis.
