Angle Protractor


A protractor is a measuring instrument, typically made of transparent plastic or glass, for measuring angles. Most protractors measure angles in degrees (°). Radian-scale protractors measure angles in radians. Most protractors are divided into 180 equal parts.They are used for a variety of mechanical and engineering-related applications, but perhaps the most common use is in geometry lessons in schools.Some protractors are simple half-discs. More advanced protractors, such as the bevel protractor, have one or two swinging arms, which can be used to help measure the angle.Soft Apps Developer provide Measure Angle Protractor tools app for measuring angle, and slope. Measure Angle Protractor is in the 1st set of the Smart Tools collection (angle, slope, level).This app measures the angle and the slope of an object.  It helps you measure the angle of everything conveniently and accurately with your phone anywhere, anytime. Measure Angle Protractor is very easy to use, as described below. You can also switch the protractor measurement unit between degree and radian by just a click.With Measure Angle Protractor, now you always bring an angle measuring pack with you as in your smart phone.We hope this Measure Angle protractor set is useful to you in angle measurementAccording to Wikipedia Protractors have traditionally been one-sided. This is thought to be because early manufacturing methods set the tone of future production. Unfortunately, the two number scales on a one-sided protractor often confuse learners when first learning to measure and draw angles. However, in 2009, Jake Adamson, a maths teacher working at Musselburgh Grammar School invented and patented the first two sided protractor trademarked "The Angler". This was a double sided protractor with one scale on each side, avoiding the confusion of having two scales together and enabling easier measuring and drawing of angles. "The Angler" protractor has been widely adopted by schools in the UK.KEY FEATURES:4 Angle Measuring Modes.Lock/Unlock screenCustomizable theme, Choose your best theme from setting.Display device verticality/tilt angle in plumb modeSimple & smart user interface design, HD imageKeep screen awake
