The task in the image is to identify which shapes or figures have
symmetry. Symmetry means that if you fold a shape along a line (called the axis of symmetry), the two halves will match perfectly.
Steps to Solve:
1.
Understand Symmetry: A shape has symmetry if it can be divided into two identical halves by a line (vertical, horizontal, or diagonal).
2.
Examine Each Figure: Look at each figure and determine if it can be folded along a line such that both sides match exactly.
3.
Circle the Symmetrical Figures: Mark the figures that exhibit symmetry.
Analysis of Each Figure:
1.
Head with Hair:
- This figure does not have symmetry because the hair on one side does not match the other side when folded vertically or horizontally.
-
Not Symmetrical
2.
Flip-Flops:
- These are identical and symmetrical along a vertical axis. If folded vertically, both sides match perfectly.
-
Symmetrical
3.
Envelope:
- The envelope is rectangular and can be folded vertically or horizontally to match both sides.
-
Symmetrical
4.
Necklace with Pendant:
- The necklace has a pendant that disrupts symmetry. Folding it vertically or horizontally will not result in matching halves.
-
Not Symmetrical
5.
Flower:
- The flower has petals that are evenly spaced and can be folded along multiple axes (both vertical and horizontal) to match perfectly.
-
Symmetrical
6.
Hamburger:
- The hamburger can be folded vertically down the middle, and both sides will match perfectly.
-
Symmetrical
7.
Star:
- The star can be folded along multiple axes (both vertical and horizontal) and still match perfectly.
-
Symmetrical
8.
Shirt:
- The shirt is asymmetrical because the sleeves and design do not match when folded vertically or horizontally.
-
Not Symmetrical
9.
Whale:
- The whale is asymmetrical due to its tail and body shape. Folding it vertically or horizontally will not result in matching halves.
-
Not Symmetrical
10.
Pencil:
- The pencil is asymmetrical because the eraser end and the sharpened end do not match when folded.
-
Not Symmetrical
11.
Knitting Ball:
- The knitting ball is round and can be folded along any axis to match perfectly.
-
Symmetrical
12.
Cake:
- The cake can be folded vertically down the middle, and both sides will match perfectly.
-
Symmetrical
Final Answer:
The symmetrical figures are:
- Flip-Flops
- Envelope
- Flower
- Hamburger
- Star
- Knitting Ball
- Cake
Circled Solution:
- Circle the following figures: Flip-Flops, Envelope, Flower, Hamburger, Star, Knitting Ball, Cake.
Final Answer Boxed:
\[
\boxed{\text{Flip-Flops, Envelope, Flower, Hamburger, Star, Knitting Ball, Cake}}
\]
