Let’s go through each shape one by one to decide if the dotted line is a line of symmetry.

A line of symmetry means: if you fold the shape along that line, both halves match perfectly — like mirror images.

---

Shape 1 (Star with vertical line):
The star is symmetric left-to-right. The vertical line splits it into two matching halves.
→ Yes

Shape 2 (Rectangle with diagonal line):
A rectangle folded along a diagonal does NOT make matching halves — the corners don’t align.
→ No

Shape 3 (Parallelogram with vertical line):
This slanted shape — folding vertically won’t make the sides match. Left and right are not mirror images.
→ No

Shape 4 (Diamond/rhombus with vertical line):
A diamond shape usually has symmetry. This one is symmetric left-to-right. Fold it — matches!
→ Yes

Shape 5 (Kite-like shape with vertical line):
Looks like a kite — top and bottom may differ, but left and right? Yes, they match. Vertical line works.
→ Yes

Shape 6 (Heart with vertical line):
Hearts are classic symmetric shapes. Vertical line down the middle — perfect match.
→ Yes

Shape 7 (Pentagon with diagonal line):
This pentagon is irregular. The diagonal line doesn’t split it into matching halves.
→ No

Shape 8 (Trapezoid with vertical line):
This trapezoid looks symmetric left-to-right. Vertical line through center — yes, matches.
→ Yes
