EARTH WITHOUT ART IS JUST EH!?
“El mayor peligro para la mayoría no reside en establecer una meta demasiado alta y fracasar, sino en establecerla demasiado corta y conseguirla”. Michelangelo Buonarroti
It is time to get started with the compass! We will draw two VERY IMPORTANT constructions, used in technical drawing to construct almost everything, EVEN A KITE!
It is CRUCIAL that you learn how to do them by observing and practising. SO LETS DO IT!:
PERPENDICULAR BISECTOR LINE
Definition:
The perpendicular bisector is a PERPENDICULAR line
that DIVIDES a line segment into TWO EQUAL parts. It also makes a right
angle with the line segment. Each point on the perpendicular bisector
is at the same distance from each of the endpoints of the original line
segment.
It is basically a line which cuts a line segment into two equal parts at 90°.
ANGLE BISECTOR LINE
Definition:
It is a line that DIVIDES the angle in TWO EQUAL parts.
The addition of two segments
is another segment that begins at the origin of the first segment and ends at
the end of the second segment.
The length of the new segment
is the addition of the measures of those two segments.
b) Subtrating
The subtration of two segments
is another segment that takes as the origin, the end of the smaller
segment and as the end, the end of the biggest segment.
The length of the segment difference is equal to the subtraction of the lengths of two segments.
2.2. Line Bisector
The line
bisector is a perpendicular line that passes through the midpoint of the
segment, so it divides the segment in two equal parts.
THEORY EXTRA (NOT FOR THE ARTBOOK)
2.3. How to divide a line segment into equal parts (Thales theorem)
1. Draw a ray that shares the origin of point A
with the line segment segment AB.
2. Mark
in the ray as many equal units as you want to obtain starting from point A. In this case, we are goint to divide the segment into three equal parts.
3. Join the point B with the end of the ray. For each of the divisions of the ray, draw
parallel lines to the segment joining B. The points obtained in the segment AB
represent 3 equal parts.
If you have any doubt about the process, you can watch theses videos:
UNIT 2: PARALLEL AND PERPENDICULAR LINES, SET SQUARE RULERS.
These are a few videos to give you information about parallel, perpendicular and intersecting lines and how to draw them using the set square rulers. Then feel free to get artistic!!!
DEFINITIONS:
PARALLEL LINES are lines that never join or meet.
PERPENDICULAR LINES are lines that join or meet making 90º angles (right angles)
SET SQUARE RULERS
45º Set Square Ruler (Escuadra)60º-30º Set Square Ruler (Cartabón)
How do we use the set square?
You have to handle your set square softly and with accuracy without
exercising too much pressure on them, only the needed one to avoid
movement.
PARALLEL LINES are lines that never join.
HOW TO DRAW PARALLEL LINES
The 45 set square hypotenuse (longest side) is placed attached to the line to which we want to draw the parallels (GUIDE).
The 60-30 set square hypotenuse is attached to the 45 set square leg.
Fix the 60-30 set square and move the
45 set square upwards or downwards drawing the desired parallel lines
along its hypotenuse.
PERPENDICULAR LINES are lines that join making 90º angles (right angles)
HOW TO DRAW PERPENDICULAR LINES
If we want to draw perpendicular lines to one direction, we will have to follow the first two steps as stated for parallel lines and then the following ones:
Having fixed the 60-30 set square, the
45 set square is turned until the other leg is attached to the
hypotenuse of the 60-30 set square.
Draw the perpendicular line along the hypotenuse of the 45 set square.
Let's review how to draw parallel and perpendicular lines using the triangular set squares.
Here are a few videos that show wonderfully the way Nature, Geometry and Art blend together. The three are interconnected. One can not fully exist without the other.

Animation is the process of designing, drawing, making layouts and preparation of photographic sequences which are integrated in the multimedia and gaming products. Animation involves the exploitation and management of still images to generate the illusion of movement.
HISTORY OF ANIMATION
Here is some information about Images in Motion, the History of Animation. Here is a brief trailer and introduction to PIXAR STUDIOS, founded February the 3rd, 1986, by Steve Jobs, Ed Catmull and John Lasseter.
If you have some more time, here is the full documentary about PIXAR STUDIOS.
Here is the famous and amazing speech by Steve Jobs at Stanford, 2005. But first let's get a little bit more infomation about him:
An illustration is a drawing, painting or printed work of art which explains, clarifies, illuminates, visually represents, or merely decorates a written text, which may be of a literary or commercial nature.
Another definition for illustration in Art is a visualization or a depiction made by an artist, such as a drawing, sketch, painting, photograph, or other kind of image of things seen, remembered or imagined, using a graphical representation.

SUMMARIZING
An illustration is a drawing that is related to a text. The image has the same meaning as the text and helps us to understand or enhance the idea.
An illustration illustrates or depicts an idea.
TASK
First: Check drawings online for ideas, that will help you to make up a story. Or use the Story Cubes.
Second: Draw the illustration taking into account that you have to leave some free space for the text.
Finally: Colour your drawing with colour pencils. You must apply the techniques you have learnt on the previous activity (activity 15 A)
