Step 1: A line of symmetry means the figure can be folded and both halves match exactly Step 2: A regular pentagon (5-sided figure with equal sides and angles) has 5 lines of symmetry Step 3: Check the other options: - Irregular blob: no consistent symmetry - Zigzag line: left and right halves don't match - Random scribble: no pattern or symmetry Answer: A regular pentagon has a line of symmetry.
