Looking at the worksheet, I need to determine whether each shape has symmetry along the dashed line shown.
Let me check each shape one by one:
1.
Orange triangle - The dashed line goes from top to bottom through the middle. If I fold it along this line, both sides match perfectly. This is symmetric.
2.
Teal pentagon - The dashed line goes vertically through the center. Both left and right sides are mirror images. This is symmetric.
3.
Blue star - The dashed line is horizontal across the middle. But if I look carefully, the top half doesn't match the bottom half when folded. The points don't align properly. This is NOT symmetric.
4.
Blue trapezoid - The dashed line is horizontal across the middle. The top part is smaller than the bottom part, so they won't match when folded. This is NOT symmetric.
5.
Red heart - The dashed line goes vertically down the center. Both halves are perfect mirror images. This is symmetric.
6.
Yellow smiley face - The dashed line goes vertically through the center. The eyes and mouth are centered, so both sides match. This is symmetric.
So out of 6 shapes, 4 have symmetry (triangle, pentagon, heart, smiley) and 2 do not (star, trapezoid).
Final Answer:
The shapes with symmetry are: orange triangle, teal pentagon, red heart, and yellow smiley face. The blue star and blue trapezoid do not have symmetry along the dashed lines shown.
