A protractor is used to draw and measure angles. An angle is the amount of turn between two lines. Angles are measured in degrees with the symbol °. Angles can be labelled with 3 letters (eg DEF) to ...

If you've ever found yourself wanting to measure something but don't have a ruler or tape measure on hand, measuring apps on your phone can come to the rescue. They range from the fairly simple to ...

Your iPhone’s camera can do more than just take photos. It can also help you record measurements for do-it-yourself projects. I recently tested two apps—one that lets you record measurements on the ...

Smartphones are useful for a lot of things. You can even use one as a ruler in a pinch. Generally speaking, you won’t replace your trusty yard stick. A phone is simply too small for anything other ...

Imagine a world where you never have to bend the tape measure. Actually don't, because that world is already here. While we've all been awkwardly trying to snap the tape measure into an L shape when ...

Do you think there’s a triangle whose angles measure 41, 76 and 63 degrees? At first, answering this may seem easy. From geometry class we know that the sum of the measures of the interior angles of a ...

Heralded as the industry’s first five-beam, wide-angle distance sensors, the GP2Y3A components feature a 25° wide measuring angle achieved by five triangulation detections in one package. They are ...

Most light-field sensors — devices that detect the angles of incoming light rays to reconstruct 3D scenes — can detect light only in the ultraviolet and visible wavelength ranges. A newly developed ...

An angle is the amount of turn between two lines. An angle is measured in degrees (°). Angles are a way of describing the space between 2 lines that begin at the same point. They are a measure of how ...
