This document provides instructions for technical drawing tasks involving angles, dividing segments, drawing angles off lines, using straight lines to create a sense of volume, and identifying how an artist used lines to create depth. Learners are asked to answer questions about drawing 45 and 60 degree angles using triangular set squares, dividing a 77mm segment in half with a compass, drawing a 72 degree angle from a point on a line using a protractor, composing an illustration showing how straight lines can imply volume, and recognizing how the artist Josef Albers used black lines to create a sense of depth in his painting "Homage To The Square: Glow".

1. Technical Drawing: materials, signs and lines By Elena

2. Tasks Unit 5 1. Answer the following questions about Technical Drawing: a.- What angles can you draw using a 45º triangular set square? And with a 60º triangular set square?

3. b.- Divide a 77 mm segment into two equal parts, using your compass. b- F1 to F2: 77mm

4. c.- Draw a straight line and any point A on it. Starting at point A, draw a 72º angle off the line using a protractor.

5. d.- A straight line can create a sense of volume. On a sheet of paper, draw a composition showing this effect

6. 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? The painter creates a sense of depth with black lines.
