01 What does an artist commonly compare when measuring proportion with a pencil?
Answer and explanation
Correct answer: C. Length, angle and relative size
Explanation: In observational drawing, an artist may hold a pencil at arm’s length to estimate and compare dimensions, alignments and angles. The pencil can help judge the height of one part against another, the angle of a contour and the relative size of objects. Therefore, option C is correct. Counting colours, judging only shadow depth or knowing the paper’s price does not measure proportion. Proportion depends on relationships among lengths, angles and sizes.
