Appreciating the Protractor
And that is the right answer. And then we can get another angle. So let's try to measure this one right over here. So once again, place the center of the protractor at the center, at the vertex, of our angle. We can place the 0 degree, the base of the protractor, at this side of the angle. So let's just rotate it a little bit, maybe one more time.How to Measure an Angle Using a Protractor | Sciencing
The Protractor. We all know that construction is more than just 90° angles. The protractor, used for measuring angles, has a possible history that dates back to around 1400 BCE. In the tomb of an ancient Egyptian architect, Kha, researchers discovered a unique shaped object that has been debated over for many years. It’s been recently suggested that this object is in fact the world’s first known protractor.Using a Protractor - MATH
Using a Protractor. The best way to measure an angle is to use a protractor. To do this, you’ll start by lining up one ray along the 0-degree line on the protractor. Then, line up the vertex with the midpoint of the protractor. Follow the second ray to determine the angle’s measurement to the nearest degree.

Place the protractor so that one of the lines of the angle you want to measure reads zero (that’s actually 0°). Using the zero line isn’t necessary because you can measure an angle by getting the difference in the degree measures of one line to the other. It’s easier, however, to measure the angle when one side of it is on the zero line.Protractors - Precision Measuring Tools - Grainger ...
So, to know the degrees that an angle measures, we need to place the straight part of the protractor over one of the sides of the angle, making the vertex and the central point of the protractor...Measuring Guide - Springs Window Fashions
Protractor. A protractor is a transparent plastic tool designed to measure angles. They are usually semicircular but also are available in a full circle 360° version. The small hole near the bottom of the protractor is aligned over the vertex of the angle to be measured.Protractor™ on the App Store
A protractor is commonly used to measure angles. Protractors are usually circular or semi-circular and made of transparent plastic, so that they can be placed over shapes drawn on a piece of paper, allowing you to take a measurement of the angle.Online Protractor | Angle Measuring Tool
Follow the top line of the angle up to the measurements on the protractor's arc. Step4. If the lines of the angle measure are short like the picture below then to get an accurate measurement, extend the angle's line until it passes the protractor.Protractor - Wikipedia
place the centre of the protractor on the vertex Y of angle XYZ. Let the reference line of the protractor coincide with ray YZ of the angle. Find the 'zero' mark on the reference line of the...Angles - Measuring Archives - Maths Zone Cool Learning Games
A goniometer is an instrument that either measures an angle or allows an object to be rotated to a precise angular position. The term goniometry derives from two Greek words, gōnia, meaning angle, and metron, meaning measure.. The first known description of a goniometer, based on the astrolabe, was by Gemma Frisius in 1538.Construction Protractors | Amazon.com | Measuring & Layout ...
A possible approach. If your students are struggling to position the protractor in the “standard” correct way, you may wish to get them to focus on positioning the protractor’s centre on the vertex, but not worry about lining up one of the rays with 0º on the protractor, e.g. as follows:. Now students can pick either the inner or outer scale—it doesn’t matter which, and find the ...3 Ways to Measure an Angle Without a Protractor - wikiHow

The Draw2Measure Protractor app allows students to measure angles in two ways. First, students can place an angle over the screen of a device, such as a phone or tablet, and trace along the sides of the angle with a fingertip or stylus. The app records the locations of the sides and then calculates the angle.Angles | Education.com

Finding the missing angle is also a concept we have worked on. Angle COA is a straight angle and therefore measures 180 degrees. We know that angle BOA measures 44 degrees. We can subtract the known angle from the large angle to determine the missing angle (180 - 44 = 136). Angle COB would measure 136 degrees.Get Angle Protractor Pocket - Microsoft Store en-GB
