ABOUT THE SYMETRY

Symmetry: Is when some shapes are a reflection of other. It´s only on same shapes.
Reflection symmetry: Is a quality of same shapes that consists in having an axis between two shapes, and it's like when you see you in a mirror.
Symmetry axis: Is when a line divides in two symmetrical parts. Every element of the shape is represented in the other part at the same distance from the axis. Symmetrical points are on perpendicular lines to it.
Central symmetry: Its a reflection of a shape without an axis, so there is a symmetry centre. Every element of the shape is represented in the other part at the same distance from the symmetry centre. Symmetrical points are collinear with the centre.
Geometric symmetry: Is a kind of symmetry which follows accurately (presition9 the geometric symmetry rules.
Apparent symmetry: Is a quality of shapes or objectswhich shows an obvious symmetry, but not every elements follows this rules. It happens very frecuently in nature.

Symmetrical balance: Is a way to organize parts of an image, picture or drawing, so one side mirrors (duplicates) the other. The opposite way is called Asymmetrical balance.

the puntillism

What is Puntillismo:
Pointillism, also known as neo-impressionism, dot painting or divisionism, was a painting technique created in France, in the mid-1880s, in which it consists of the decomposition of tones based on tiny brushstrokes, similar to small points of colors. The word puntillismo is of French origin pointillisme.


The technique of pointillism was developed from the impressionist movement and focuses on the production of color through juxtaposed brushstrokes, that is, because the colors are pure and never mix with each other but the viewer is the one who does it. However, the evolution of impressionism to pointillism is due to the scientific studies of Michel Chevreul (1786-1889), he published his work Of the law of the simultaneous contrast of colors (1839) and Hermann von Helmholtz (1821-1894) investigated on the theory of colorful vision trichromatic (1878).

Characteristics of pointillism

As was previously said, pointillism was a technique created from the impressionist movement, so the decomposition of colors and luminosity, the way to create the dimension and depth, as well as the preference to make the paintings outdoors with the In order to capture light and color are characteristics attributed to that movement.

However, pointillism is more focused on the geometric cut or the scientific search for color to obtain more luminous tones that allow light and heat to be transmitted. Also, pointillism used the juxtaposition of primary colors separated by very small white spaces that ends up mixing the images and colors, producing a third color, which seeing the painting at a distance allows a dotted image to be continued to be mixed in the eyes of the observer , which produces the impression of a whole.

Therefore, the tone is the decomposition from the primary colors, which allow to arise secondary colors that constitute the shape of the represented objects, once the prismatic alteration of the color enhances the impression and tones.

Representatives of pointillism and their works

The maximum representatives of pointillism were:

Paul Signac (1863-1935): considered as the father, creator, or initiator of pointillism. He painted among many works, The port of Marseille, The red buoy, Breakfast.

Georges Seurat (1859-1891): among his works highlights the circus, models, the Seine and the Big Jatte in spring.

Also, the artists were influenced by pointillism: Van Gogh (1853-1890), Henri Matisse (1869-1954) and Pablo Picasso (1881-1973).

GEOMETRY

Geometry: is a science that studies the shapes, the points and the lines. It comes from the Greek words "geo" and "metry".
Point: is the place where two lines intersect.
Line: is an infinit write of a sucesion of infinit points.
Ray: it´s a line that has beggining and doesn´t have end.
Line segment: it´s a line with two endpoints.
End point: is the point where a ray or a segment line ends or starts.
Freehand: draw without any instruments of drawing.
Compass: it´s an instrument to make circles and arcs and take messures.
Length: measure of something from end to end.




DEFINITIONS ABOUT ANGLES AND LINES
Parallels: lines which never intersect themselves.
Perpendicular: two lines that when intersect, they form four right angles.
Oblique: lines that aren´t perpendiculars and parallels.
Angle: two lines that have a common point (vertex).
Right angle: angle of 90º
Obtuse angle: angle of more than 90º
Acute angle: angle of less than 90º
Flat angle: angle of 180º
Complet angle: angle of 360º
Complementary angles: two angles that form 90º
Suplementary angles: two angles that form 180º

DEFINITIONS ABOUT CIRCLES
Circle: set of points at the same distance to the center
Circumference: it's the full length of a circle. The complete distance a round a circle is the perimeter
Center: point equidistant to any of the points of a circle
Radius: it´s a line from the center and the perimeter
Diameter: line segment that goes from a point of the perimeter to another point, passing for the center of the circle
Chord: line that connects two points of the circle not through the center
Arc: segment of a circle
Arrow: segment that divides an arc in the middle. It´s the center of the chord
Tangent: line that only touch a point of a circle
Outer: element that doesn´t touch the circunference
Inner: element inside the circumference
Concentric circles: circles with different radius but place in the plane s

HALLOWEEN HISTORY

                                    HALLOWEEN HISTORY  

Halloween is an annual holiday, celebrated each year on October 31, that has roots in age-old European traditions. It originated with the ancient Celtic festival of Samhain, when people would light bonfires and wear costumes to ward off ghosts. In the eighth century, Pope Gregory III designated November 1 as a time to honor all saints; soon, All Saints Day incorporated some of the traditions of Samhain. The evening before was known as All Hallows Eve, and later Halloween. Over time, Halloween evolved into a day of activities like trick-or-treating and carving jack-o-lanterns. Around the world, as days grow shorter and nights get colder, people continue to usher in the season with gatherings, costumes and sweet treats.
