UNIT 2: PARALLEL AND PERPENDICULAR LINES, SET SQUARE RULERS.

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

1. The 45 set square hypotenuse (longest side) is placed attached to the line to which we want to draw the parallels (GUIDE).
2. The 60-30 set square hypotenuse is attached to the 45 set square leg.
3. 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:

1. 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.
2. 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.

UNIT 1: INTRODUCTION TO GEOMETRY.

INTRODUCTION: Geometry, Nature and Art. 

THE MAGIC OF GEOMETRY

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. 

 "NATURE BY NUMBERS" (Golden Ratio, and the Fibonacci Seies) a 3D animated short film by Cristobal Vila. 

"INFINITE PATTERNS" also by Cristobal Vila. 

"MATES APLICADAS" by José Ramón Soriano.

UNIT 6: REGULAR POLYGONS

This term we will continue with GEOMETRY by designing a beautiful mandala. But first we will check our knowledge about regular polygons. Here is a few videos to help us.

 REGULAR POLYGONS AND ORIGAMI




I found a very interesting page to revise and check your knowledge of the Basic Geometry Terms with pictures. Check it out!

Here is another link  to go over "the basics of geometry", some of them we have already seen before.



UNIT 6: THE CIRCUMFERENCE AND THE CIRCLE

Circumference

The circumference is the outline of a circle.

Circle

A circle is a flat shape made by drawing a curve that is always at the same distance from the centre. 

 

The Radius is the distance from the center to the edge.
The Diameter starts at one side of the circle, goes through the center and ends on the other side.
The Circumference is the distance around the edge of the circle, that is the outline of the circle

Note that the Diameter is twice the Radius:

Diameter = 2 × Radius

Lines

A line that goes from one point to another on the circle's circumference is called a Chord.
If that line passes through the center it is called a Diameter.
A line that "just touches" the circle as it passes by is called a Tangent.
A line that intersects the circle is called intersecting or secant line.
And a part of the circumference is called an Arc.

 Slices

There are two main "slices" of a circle. The "pizza" slice is called a sector. And the slice made by a chord is called a segment.

Common Sectors

The Quadrant and Semicircle are two special types of Sector:

	Quarter of a circle is called a Quadrant.             Half a circle is called a Semicircle.

UNIT 5: GEOMETRIC SHAPES IN ART

GEOMETRIC SHAPES IN ART

ACTIVITY 1: SEVEN SHAPES PROJECT

The seven shapes Project consists of using seven different geometric shapes or the same shape repeated seven times like the following example.

  
 ACTIVITY 2: BECOME AN ARTIST USING GEOMETRIC SHAPES

Where can we find Geometry in Art? Well, this is your project. You are going to become an Artist using Geometric Shapes. Check the following Artists and base your work on one of their works of Art.  

STEPS: 

1 - You select an Artist (from the list below or a different one that you like) and search about his/her works of Art and his/her life. 

2 - You choose one of his/works of art and print it. 

3 - You became an Artist! It is not about imitating, it is about using the work of Art you printed as an inspiration for your own work of Art. 

ARTISTS USING GEOMETRIC SHAPES

- Victor Vasarely 

- Piet Mondrian

- M.C. Escher

- Wassily Kandinsky

- Kazimir Malevich

- Pablo Picasso

- George Braque

PROJECTS

PROJECTS 

Information for your projects

1. Think about an interesting, creative and original idea that you can share in class. 
2.  Choose a partner to work with, share your ideas.
3. Send an email with the following information: 
1. Title for your project
2. Authors (name, surnames and group). Between 2 and 5 authors.
3. Brief description of your project (2-5 lines)
4. Materials needed.
5. Write a guideline that you will use in class to explain your project step by step. (Do not forget an introduction, the steps to follow and the closing)

IMPORTANT THINGS FOR THE PROJECT

1. Make sure it can be done in one or maximum two classes. Practice with someone else before the real presentation in class.
2. Make sure you have an example that we can see. 
3. Make sure everybody can bring the material. Bring some material extra. 
4. Do not forget to close your presentation 5 or 7 minutes before the class is over to give time to pick things up and clean the desks.
5.  ENJOY IT!

EXAMPLE FOR A PROJECT 

"HOW TO MAKE A GOANIMATE VIDEO FOR A PRESENTATION"

OUR NEXT TASK: CUBIST SELF-PORTRAIT

NEW CHALLENGE: THE CUBIST PORTRAIT

We have worked the line, now we go a step further and we work the value. But this time we will create a cubist portrait. Lets see this presentation first to revise your knowledge on "value" and the four different ways of shading. We will practice shading to create original cubist portraits.

 

 

ACTIVITY: CUBIST SELF PORTRAIT

Assessment Criteria (do not forget to copy this at the back of your work) 

1.Draw a margin or a frame or a background (1 point)

2. Use shading and lines to create the impression of a cubist portrait (3 points)

3. Originality, creativity (1 point) 

4. Expressiveness (2 points)

5. Neatness, good presentation (1 points)

6. Description of your work, minimum 5 sentences (1 point)

7. Self evaluation (1 point)

SELF PORTRAIT

Here is a presentation with a little bit of history about the self portrait in art history, and another presentation about the line, one of the elements of Art.:

UNIT 1: VISUAL ELEMENTS OF ART

The elements of art are shape, form, value, line, color, space and texture. This term we will work combining the different visual elements of art, starting with a SELF PORTRAIT.

Check these presentations to get a better idea:
