Let us draw some human figures. Measure your friend's body—the lengths of their head, torso, arms, and legs. Write the ratios as mentioned below— head : torso ___ : ___ torso : arms ___ : ___ torso : legs ___ : ___. Now, draw a figure with head, torso, arms, and legs with equivalent ratios as above. Does the drawing look more realistic if the ratios are proportional? Why? Why not?
Answer:
When the drawn figure has the same proportional ratios as the measured person, the drawing appears more realistic because it maintains the correct body proportions.
Drawings with incorrect proportions (like a very large head or very short legs relative to the torso) appear distorted or cartoon-like rather than realistic.
Conclusion: ∴ Yes, the drawing looks more realistic when the ratios are proportional because human visual perception expects certain proportional relationships in human figures.
Explanation
This activity connects proportional reasoning to real-world applications in art and drawing. The chapter explains that proportional relationships define how realistic a drawing appears. When students measure actual body proportions and replicate them in their drawings, the figures look more natural because human visual perception expects certain proportional relationships in human figures.
Solution Steps
Measure your friend's body parts: head, torso, arms, and legs.
Record the lengths of each body part.
Write the ratio head : torso using the measured values.
Write the ratio torso : arms using the measured values.
Write the ratio torso : legs using the measured values.
Draw a human figure using the equivalent ratios as measured.
Compare the proportional drawing to non-proportional drawings to determine which looks more realistic.
