What is a good way to show symmetry through line?

Correct answer: Similar lines on both sides of a centre line

The correct answer is A: similar lines placed on both sides of a centre line can show symmetry. Symmetry means that parts on opposite sides correspond in position, size, direction, or visual arrangement. A centre line is often used as a guide, especially when drawing a face, leaf, building, object, or other figure with matching sides. The guide helps the artist compare one side with the other; it need not remain visible in the final artwork. Option A is correct because corresponding lines on both sides create a mirror-like relationship. Option B is wrong because placing all lines on one side removes the needed correspondence. Option C is wrong because a dark side and an empty side create unequal visual weight and asymmetry. Option D is wrong because removing the guide does not itself create symmetry; symmetry comes from matching placement of the drawn parts. Memory cue: symmetry means ‘same relationship on both sides,’ not merely a visible centre line.
