Technicaldrawing: Materials Sings lines ByAnder Martin
a.- What angles can you draw using a 45º triangular set square? And with a 60º triangular set square?
b.- Divide a 77 mm segment into two equal parts, using your compass.
c.- Draw a straight line r and any point A on it. Starting at point A, draw a 72º angle off the line using a protractor.
d.- A straight line can create a sense of volume. On a sheet of paper, draw a composition showing this effect
e.- Look for a picture painted by Josef Albers which he uses only black and red straight lines, and for the picture named "Homage To The Square: Glow" painted in 1966 by the same author. In which one does the painter create a sense of depth? http://www.hirshhorn.si.edu/visit/collection_object.asp?key=32&subkey=3042
