Young children can be given symmetrical shapes (e.g., isosceles triangles and trapezoids, rectangles, rhombuses) to put them together and see whether the combination of two (or more) symmetrical ...

A 2D shape is symmetrical if you draw a line through it and it looks exactly the same on either side of the line. Find out more in this Second Level Bitesize guide.

Polygons are multi-sided shapes with different properties. Shapes have symmetrical properties and some can tessellate. Loci and constructions - Edexcel Loci are a set of points with the same ...

Symmetry tends to dominate; that is, we usually see the shapes defined by mirror-symmetric contours as figure rather than as ground (c). Our brain is choosing symmetry to perceive objects.

Crows in a lab were able to distinguish shapes that exhibited right angles, parallel lines, and symmetry, suggesting that, like humans, they have a special ability to perceive geometric regularity.
