PART I – Concepts in Symmetry

Study Period

Focus Image

Question
Describe the symmetry of this logo.

Your Observations
(no more than 50 words) (2 marks)
This logo is a 6-fold rotation symmetry with no reflection symmetry. It could be rotated but it possesses no mirror lines, hence there is no reflection symmetry.

Week 1

What was the most surprising or interesting fact you learnt from
Week 1 lectures

Describe the symmetrical elements you see in this
Japanese embroidery.

(no more than 20 words) (2 marks)
It is my first time learning about rotation symmetry and previously did not know that some logo/designs could be rotated and return to the same pattern.

(no more than 50 words) (2 marks)
This Japanese embroidery has 4 mirror lines of which 2 are unique mirror lines
(horizontal + vertical and 2 diagonally). It has a 4 fold rotation symmetry, which means that it could be rotated at 90° without changing its form.

Week 2
Image 2

Can you add anything to your Week 1 description of the logo?

(no more than 20 words) (2 marks)
The logo uses the primary colours red, green and blue which helps to add on to the synchronization of the logo.

PART II – Plane (2D) and Space (3D) Symmetry

Question
Use the formal descriptors of plane symmetry to describe this bathroom tile tessellation. Your Observations
(no more than 50 words) (2 marks)
This bathroom tile tessellation possesses plane symmetry of p4mm. There is also a
4 fold rotation symmetry and two pairs of mirror lines. It can also be a unit cell that could be used to replicate the bathroom tiles.

There is something weird in Image 4. Was Paul
Rand correct – geometry is never wrong?
