In this video I will show you step by step how to reflect points across a line of symmetry that you can translate to other figures and graphs. Facebook @freemathvideos Instagram @brianmclogan Twitter ...

We are fond of saying things are symmetric, but what does that really mean? Intuitively we have a sense of symmetry as a kind of mirroring. Suppose we draw a vertical line through the middle of a ...

Symmetry is when one side of a shape is a mirror image of the other side. Lots of buildings and everyday objects use symmetry because it looks appealing to the human eye. Watch the video below from ...

Big Idea – We can describe, measure, and compare spatial relationships. to build on students' knowledge of line symmetry and develop students' reasoning with properties of symmetry to develop an ...

A shape has a line of symmetry when the folded part sits perfectly on top with all edges matching. The number of lines of symmetry in a regular polygon is equal to the number of sides. A shape has ...

There's a part of the brain that enables us to perceive magnitude -- we can compare loudness when hearing different tones or compare the number of dots in a group at a glance. Neuroscientists have ...

Receive emails about upcoming NOVA programs and related content, as well as featured reporting about current events through a science lens. Symmetry also has an aesthetic meaning, although this is ...

In his new book Creating Symmetry, Frank Farris uses ideas from advanced mathematics, such as complex analysis and abstract algebra, to transform snapshots of landscapes, flowers, or even his dinner ...

A group of mathematicians has shown that at critical moments, a symmetry called rotational invariance is a universal property across many physical systems. For more than 50 years, mathematicians have ...
