Symmetrical and Asymmetrical Figures Object Pattern
Symmetrical figures:
number Pattern
examples:
(a) +2 +2 +2 +2 +2 +2 +2 +2
2 4 6 8 10 12 14 16 18
Asymmetrical figures: (b) 1 × 1 = 1
11 × 11 = 121
111 × 111 = 12321
1111 × 1111 = 1234321

Mirror Image or reflection
tessellation
Tessellation is a pattern of geometric shapes
that fill a 2D space without any gaps and no
Coding and decoding overlaps.
example:
Coding is a method of expressing some
messages in a secret way.
example:
HAPPY BIRTHDAY!
8 1 16 16 25 2 9 18 20 8 4 1 25!
Challenge Question Critical Thinking
In the given space, draw a geometrical figure that:
1. does not have any line of symmetry. 2. has one line of symmetry.
3. has two lines of symmetry. 4. has more than two lines of symmetry.
