And the rhombus matches twice, so the order is 2. If a 2D shape can be folded in half, with either side of the fold being a mirror image of the other, then it has a line of symmetry. A line of ...

A 2D shape is symmetrical if you can draw a line through it and it looks exactly the same either side. This line is called a line of symmetry. Oh that rather smug expression tells me that square knows ...

This course explores some visual aspects of mathematics. Topics are chosen from areas such as geometric constructions, tessellations of the plane, symmetry groups, Platonic and Archimedean solids, ...

The human visual system exhibits a remarkable ability to decipher the three-dimensional structure of the world from two-dimensional retinal images. Central to this process is the utilisation of shape ...

Peg uses a magic ukulele to find the line of symmetry on shapes. Peg uses a magic ukulele to find the line of symmetry on shapes that form steps. The steps should lead her to the Kingdom of Day, where ...
