Scientists tested crows on their ability to recognize “geometric regularity,” a skill previously assumed to be unique to ...

Perimeter doesn’t have to be hard! Learn how to calculate it quickly for any shape — with tricks they never taught you in ...

Crows can recognize geometric patterns, suggesting that humans aren't unique in understanding shape structure.

In a remarkable new study, crows demonstrated an intuitive grasp of geometry—identifying irregular shapes without training.

Crows in a lab were able to distinguish shapes that exhibited right angles, parallel lines, and symmetry, suggesting that, ...

The perimeter is the distance around the outside of a 2D shape. The distance can be measured in units like millimetres, centimetres, metres and kilometres. To work out the perimeter, add up the ...
