When you hear the word symmetry, you might think generally of triangles, butterflies, or even ballerinas. But defined scientifically, symmetry is _a transformation that leaves an object unchanged." Huh? Colm Kelleher unpacks this...

This video explains what rotational symmetry is, and how to find the order of rotational symmetry of a shape. Practice questions and answers are at the end of the video. This is an updated, 4K version of our previous video.

This video provides a range of practice questions and answers on the topic of rotational symmetry.

This short video explains why the order of rotational symmetry of a circle is infinite.

This video will guide you through some practice GCSE style questions on the topic of symmetry.

Through real life examples and animation, this video shows students that when an object is symmetrical, it has the property of symmetry and that the line of symmetry is the line of reflection. Students will come to understand that many...

Symmetry and optical activity are intricately linked in organic molecules. A molecule is optically active if it can rotate the plane of polarized light. Optical activity arises from the molecule’s lack of symmetry—specifically, its...

This video will be the perfect way to introduce your class transformations. Students will learn that a flip is a reflection, a slide is a translation, and a turn is a rotation, while also reviewing the concepts of symmetry and dilations,...

We investigate the symmetries contained in the walls of the Alhambra, and spiritual nature of mathematics. When something is true mathematically, it is true forever. The Islamic Moors recognized parallel between that thought and their...
