Two effective manipulatives that can be used to support fractions and base 10 learning are base 10 blocks and Cuisenaire rods ...

In geometry, parallel lines are straight lines that run alongside one another and never intersect. They share a common trait, which is that they maintain a constant distance between them. Determining ...

The original version of this story appeared in Quanta Magazine. Standing in the middle of a field, we can easily forget that we live on a round planet. We’re so small in comparison to the Earth that ...

Understanding the relationships between lines – whether they run side-by-side, diverging into infinity, or intersect at a perfect right angle – is fundamental to geometry and a cornerstone of ...

On 10 wooded acres outside of Tallahassee, Florida, a curved, wood-paneled home juts out of the natural landscape like a ship that’s been permanently grounded on land. It’s the only residence designed ...

If you drive a car built since 2018, a rearview camera came standard, but they actually started popping up as options on cars more than a decade before that. And while many early examples were ...

Horizontal lines run left to right, parallel to the horizon, with slope 0 and equation y = k. Vertical lines run top to bottom, perpendicular to the horizon, with undefined slope and equation x = k.

THIS is a philosophical thesis by a writer who is really familiar with the subject of non-Euclidean geometry, and as such it is well worth reading. The first three chapters are historical; the ...

Can you imagine the imprint a four-dimensional hexagon might leave as it passes through your three-dimensional kitchen table? Probably not, but some people can. One such person was mathematician ...

Crows are able to look at a handful of four-sided shapes and correctly distinguish those that exhibit geometric regularity from those that don't, according to a provocative new study. It's the first ...

Abstract: Telecentric fringe projection profilometry (TFPP) is an important solution for 3-D measurement of micro-objects. In a TFPP system, the fringe projection angle affects the sensitivity of the ...
