º1. Answer the following questions about TechnicalDrawing:1.a.- What angles can you draw using a 45º triangularset square? And with a 60º triangular set square?
1.b.- Divide a 77 mm segment into two equal parts,using your compass.
1.c.- Draw a straight line r and any point A on it.Starting at point A, draw a 72º angle off the line using aprotractor.
1.d.- A straight line can create a sense of volume. Ona sheet of paper, draw a composition showing thiseffect :
1.e.- Look for a picture painted by Josef Albers whichhe uses only black and red straight lines, and for thepicture named "Homage To The Square: Glow" paintedin 1966 by the same author. In which one does thepainter create a sense of depth?It doesn`t createsense of depthIt creates a senseof depthhttp://www.hirshhorn.si.edu/collection/home/#collection=josef-albers&detail=http%3A//www.hirshhorn.si.edu/bio/josef-albers-innovation-and-inspiration/http://www.hirshhorn.si.edu/search-results/?edan_search_value=albers
1. Answer the following questions about Polygonalshapes: triangles and quadrilaterals:1.a.- What is a triangle? Write a definition.DEFINITION:a triangleis a flat shape formed by threestraight lines that intersect each other.
1.b.- Describe the characteristics of a quadrilateral.What quadrilaterals can you name?-They have four angles-The sum of the angles is 360º-They have four sidesrectanglesquare
1.c.- Name and define the important lines of a triangle.Hypotenuse:is the largest side.Other sides(called “catetos” in spanish):are the twoshortest sides.
1.d.- What is a trapezoid? How is it different fromquadrilaterals called parallelograms?A TRAPEZOID is a quadrilateral but it isnt aparallelogram.None of its sides are equal norparallel,all its angles and diagonals aredifferents.The angles are not right-angles and thediagonals are not parallels.
A triangle with sides that measure 65, 55 and 45 mm.1.e.Draw the followin triangles and quadrilateralsgiving step-by-step diagrams.Write simple eachinstructions for each step.Draw the three sides.Trace an arc withthe compass,thesame lenght as thesecond side.Draw another arc thesame lenght as thefirst side.Complete the triangleby joining the first thesecond and the thirdside.
A diamond with the longest diagonal measuring 60mmand its smallest diagonal measuring 50mm.Use the compasstotrace the arcs.Then join thepoints.Draw two straightlinesperpendicular toeach other.
A trapezoid with sides measuring 45, 40, 35 and 30mm and a diagonal of 50 mmDraw the known diagonal.Using a compass trace arcswhich are the same lenghtas all the known sides,from each endpoint of thediagonal.The four verticesare where the arcsintersect.Join points to make thetrapezoid.
f.- Find a picture by Richard Anuszkiewicz that usesjust triangles.http://www.hirshhorn.si.edu/collection/home/#=richard anuskiewicze
1.g.- Look for the picture "Grande Toile Grise PourKassel" painted by Antoni Tapies in 1964. Whatpolygonal shapes can you see?http://www.artium.org/Castellano/Colecci%C3%B3n/Exposiciones/LaColecci%C3%B3nenArtium/tabid/153/language/es-ES/Default.aspxI can see:squares,rectangles.
h.- Look for a Basque Sculptor who uses mostlypolygonal shapes in his works.This sculptureis from JorgeOteiza.http://www.guggenheim.org/new-york/collections/collection-online/show-list/do-search/
i.- Look for Pablo Picassos "Accordionist" painted in1911 and Georges Braques "Violin and Palette"painted in 1909. What movement do they belong to?What similarities can you see?http://www.guggenheim.org/new-york/collections/collection-online/show-list/do-search/http://www.guggenheim.org/new-york/collections/collection-online/show-list/do-search/CubismBoth used geometrical shapes that express breakinglines and surfaces.AccordionistViolin and Palette
