SUPPORT-(Reforç) BISECTORS-PARALLELS

Some more examples of Parallel in Art

Are all those paintings done with parallel lines?

Can you find any difference between them and the next paintings?
Are these parallel lines?
WHY there aren´t exact parallel lines?
WHICH sensations do they provide you?
WHO has painted them?

Piet Mondrian and parallel lines, parallel lines and Mondrian.

Here you have some pictures from Piet Mondrian.

What do ALL those paintings have in common?
Can you find the only one that he didn´t paint?
Why do you think he didn´t paint it?

Do you like this style? Why?
Do those pictures give you any new ideas?

DRAWING PARALLEL LINES

DRAWING PARALLEL LINES


WHAT to do? To draw some parallel lines, according to different angles.

WHERE to do it? On a thick DIN A-4 sheet.

HOW to do it?

• Divide your paper into four equal rectangles. Since we do not fold the paper,  measure both sides (length and width) and divide them (mathematically) into halves. We do not fold the paper.

(All parallel have to be 1 cm distance from others)

• First rectangle (left, up):               Draw HORIZONTAL parallel lines. Please keep the distance.
• Second rectangle (right, up):        Draw VERTICAL parallel lines: they are perpendicular to the latter.
• Third rectangle (left, bottom):      Draw a 45º angle (it´s twice on your set-square). Start drawing 30º parallel lines to the frame. (To keep the distance check it on the quiet ruler, and not on the frame.)
• Fourth rectangle (right, bottom):  Draw a 30º angle (it´s twice on your 30º-60º set square). Draw parallel lines to this angle.  (To keep the distance check it on the quiet ruler, and not on the frame.)

• Self-correct: check every line (including the frame and angles) with your rulers. 
• Overline every line with a thin black marker.

Pay attention to precision and cleanliness: speed kills!)

THE NAMES OF INSTRUMENTS

THE NAME OF INSTRUMENTS - freehand drawing

WHAT to do? To draw freehand (without rulers) all your instruments.

WHERE to do it? On a thick DIN A-4.

HOW to do it? 

• Lay your instruments on the table. 
• Observe their shape and size: you need to fit them all on your paper. 
• Draw a sketch first, and check their shape, size and proportions.
• Pay attention to both set squares: they look alike but in fact they´re very different!
• Once you have drawn them, overline them with a marker.

(You can add some colour on your work, but the target is FREEHAND DRAWING)

Here´s the list of all materials required:

RULERS: long straight ruler, 45º and 30º-60º set square.
COMPASS: one compass. Please write your name and group on it!
NOTEBOOK: one DIN A-4 notebook (for writing and sketching). It must have WHITE pages.
WORKBOOK: one DIN A-4 workbook (THICK paper). It´s used for definite works (those to be corrected)
PENCILS: one soft (0B, 1B, a.s.o.) and one hard pencil (4H, 5H,a.s.o.)

Some colours you have at home (wax, wooden crayons or markers) are welcome.

You also need a FOLDER to keep your work in. You MUST leave it in the classroom. 
You can leave your tools (compass, rulers…) also. There is a safe place for them.

EVERY MATERIAL MUST HAVE YOUR NAME WRITTEN.
