GREETINGS CARD CONTEST

Have you noticed? Christmas decorations are already up in some parts of Madrid. The school will be running a Christmas Card competition. There will be a prize for different categories, and the overall first Prize winner will be published as the School's Christmas Card and sent to all students' families. HO! HO! HO!

Here are some ideas of past contests, long ago... 

CONCURSO DE TARJETAS NAVIDEÑAS

BASES

1. Participantes.- Podrán participar todo el alumnado matriculados en el  presente curso 2024-25.

2. Formato.- Tamaño DIN A-5 (mitad del DIN A-4), no desplegable.

3. Técnica.- Puede aplicarse cualquier tipo de técnica: acuarelas, témperas, ceras, pastel, lápices de  color, tintas, técnicas mixtas, etc.

4. Tema.- Será  la Navidad. Los trabajos serán originales, descalificando las copias y, el mensaje que emitan, será puramente navideño. Será tan importante el mensaje como el acabado de la ilustración

5. Lugar y fecha de presentación.- Se admitirá una sola participación por alumno. La tarjeta llevará en el dorso nombre y apellidos del alumno, así como el curso y grupo al que pertenece (a modo de firma los datos personales), entregándose a los/las tutores/as, o profesoras de plástica antes del 10 de diciembre.

6. Premios.- Se establecen tres categorías, premios por determinar.

• Categoría 1: Alumnado de 1° y 2° ESO
• Categoría 2. Alumnado de 3° y 4° ESO
• Categoría 3. Alumnado de Bachillerato.

UNIT 5: TRIANGLES AND QUADRILATERALS

TRIANGLES 

	A triangle has three sides and three angles
	The three angles always add to 180°

TYPES OF TRIANGLES

QUADRILATERALS

Quadrilateral just means "four sides" (quad means four, lateral means side). Any four-sided shape is a Quadrilateral. But the sides have to be straight, and it has to be 2-dimensional 

TYPES OF QUADRILATERALS

General Properties 

• Four sides (edges)
• Four vertices or vertexes (corners)
• The interior angles add up to 360 degrees:

Try drawing a quadrilateral, and measure the angles. They should add to 360°

Individual Properties 

UNIT 3: BISECTORS

UNIT 3: BISECTORS

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.

UNIT 2: OPERATIONS WITH LINE SEGMENTS

2. Operations with Line Segments

2.1. Adding and subtracting line segments

       a) Adding

•  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.

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.
