It compares with === operator Two lines are intersect perpendicularly at a point in any protractor and it is called origin of the protractor. 99. The size of the angle is the turn from one arm of the angle to the other, and to measure this, we require a protractor that comes with an outer and an inner scale. At best, it can provide least count of one degree for smaller protractor and half degree for large protractors. This blade is a tapered blade. The baseline of a protractor is bisected by a vertical line at its middle point. The … 4.8 out of 5 stars 45. The value which we read from the main scale gives the angle in degrees.To be more precise the angle in the main scale which comes just before the zero marks of the vernier scale is considered.To get the angle more precisely we will now get the remaining angle in minutes. The Starrett C183 Steel Protractor is a highly useful and accurate tool for setting bevels, transferring angles, small squaring tasks, checking cutter clearances within certain limits, and many other applications. The bevel protractor is used for testing the angles very precisely. Swivel plate: The swivel plate rotates over the dial. It seems the horizontal straight-line is a base of the protractor. Hence, it is considered as a baseline of the protractor. This blade is either 150 mm or 300 mm depending on the bevel protractor. A point where the baseline and a perpendicular line get intersected at the bottom of the protractor is called the origin of the protractor. The bevel protractor is used to establish and test angles to very close tolerances. This screw is used when we set the required length of the blade with the surface of the workpiece.Stock:The stock is one of the contacting surfaces in the bevel protractor while measurement of angle. General use of bevel protractor is decreasing due to the introduction of software like CAD. FREE Shipping on orders over $25 shipped by Amazon. The vernier scale has 12 divisions on both sides of the zero and each division is 5 minutes. How do you measure an acute or obtuse angle with a protractor?

A protractor contains three factors and they play vital role in measuring the angles in geometric mathematics. However, a semicircular protractor is basically used while learning to measure the angles geometrically. It contains the graduated scale of angle from a value of   0 degrees to 360 degrees. Every one degree ($1^\circ$) is denoted by a small size line segment, every five degrees ($5^\circ$) is represented by a medium size line segment and every ten degrees ($10^\circ$) is denoted by a large size line segment. Then the minute of the angle measurement is calculated by multiplying the position of the coincident line of the vernier scale with 5 ( Five ).Then finally the angle measured using the bevel protractor is noted in degrees and minutes.In this way, we measure angle very precisely using the bevel protractor. It is made of plastic or metal and it is actually made in semicircular shape but some protractors are made in circular shape too. toBe() : passed if the actual value is of the same type and value as that of the expected value.

This instrument is capable of measuring angles with a least count of 5′ or 5 minutes.It is used to measure the angle of any workpiece. Hence, a semicircular protractor represents an angle of $180$ degrees, which is divided into one hundred eighty equal parts by marking with small line segments at the circular edge of the protractor. Illustrated definition of Protractor: An instrument used in measuring or drawing angles. One side of the surface of which the angle is to be measured is kept in contact with blade and the other side is kept in contact with the stock.When the workpiece properly come in contact with the blade and the blade is properly placed on the workpiece, the blade is locked using the blade locking screw.After that when the surface to be measured comes completely in contact with the stock and the blade, the angle is fixed using the angle locking screw.Now we see the value in the main scale which coincides with the zero of the vernier scale. The main scale or the dial scale is marked over this dial.Dial scale: This dial scale is the main part of the bevel protractor. As it moves the dial also rotates with respect to the blade and the angle value is changed in the dial scale. The system then checks for part availability. We need to move the protractor so its centre is over the last point in his journey, like in the following diagram.
