Symmetrical Or Not? Worksheets | 99Worksheets - Free Printable

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

A line of symmetry means that if you fold the shape along that line, both sides match perfectly — like a mirror image.

---

a. Square with vertical dotted line on the right side → Not in the middle. If you fold it, the left part is bigger.
→ NO

b. Triangle with vertical line down the center → It’s an isosceles triangle, and the line splits it evenly.
→ YES

c. T-shape with vertical line down the center → Both sides are identical.
→ YES

d. Arrowhead shape with vertical line down the center → Symmetrical left and right.
→ YES

e. Letter “E” with horizontal line through the middle → Top and bottom don’t match (the arms of E are only on top).
→ NO

f. Shape like a rectangle with a bite taken out on the right → The dotted line is vertical, but the cutout is only on one side.
→ NO

g. Two triangles pointing up, joined at base, with vertical line down middle → Looks symmetrical.
→ YES

h. Circle with diagonal dotted line → Any line through the center of a circle is a line of symmetry.
→ YES

i. Trapezoid with horizontal line through middle → Top and bottom are different sizes, so folding won’t match.
→ NO

j. Hexagon with diagonal dotted line → This hexagon looks regular, and the line goes from corner to opposite corner — should be symmetrical.
→ YES

k. House-like shape with vertical line down center → Left and right sides match.
→ YES

l. Rectangle tilted with diagonal dotted line → A rectangle’s lines of symmetry are only vertical and horizontal through center — not diagonal. Folding diagonally won’t match.
→ NO

*(Note: The last one is labeled “d.” again in the image, but we’ll call it “l.” for clarity.)*
