Geometric intersection graphs form an intriguing class of structures in which vertices represent geometric objects – such as line segments, discs, or curves – and an edge is established between two ...

There is a long, beautiful history of thinking about numbers and shapes as two aspects of the same idea. Square numbers are often described using arithmetic: 1 = 1 x 1 = 1, 2 = 2 x 2 = 4, 3 = 3 x 3 = ...

You will need to be confident with arithmetic sequences and the 𝑛th term rule to understand these other types of sequences. A geometric sequence contains numbers that are multiplied by a certain ...

Often when describing patterns, they are placed in one of two categories: organic or geometric. Organic designs are ones ...
