- Because your not using the protractor right!
- sometimes we need to use protractors to find the exact answer of degrees.
Degrees (Angles) We can measure Angles in Degrees. There are 360 degrees in one Full Rotation (one complete circle around). Angles can also be measured in Radians. (Note: "Degree" is also used for Temperature, but here we talk about Angles)

An angle is a form of geometrical shape, that is constructed by joining two rays to each other at their end-points. The angle can also be represented by three letters of the shape that define the angle, with the middle letter being where the angle actually is (i.e.its vertex). Angles are generally represented by Greek letters such as θ, α, β, etc. ...
There are majorly six types of angles in Geometry. The names of all angles with their properties are: 1. Acute Angle: It lies between 0° to 90. 2. Obtuse Angle: It lies between 90° to 180° 3. Right Angle: The angle which is exactly equal to 90° 4. Straight Angle: The angle which is exactly equal to 180° 5. Reflex Angle: The angle which is greater t...
In case of a polygon, such as a triangle, quadrilateral, pentagon, hexagon, etc., we have both interior and exterior angles. 1. Interior angles are those that lie inside the polygon or a closed shape having sides and angles. 2. Exterior angles are formed outside the shape, between any side and line extended from adjacent sides. For example, an imag...
Positive Angle- An Angle measured in Anti-Clockwise direction is Positive Angle.Negative Angle- An angle measured in Clockwise direction is Negative Angle.Vertex- The corner points of an angle is known as Vertex. It is the point where two rays meet.Arms– The two sides of angle, joined at a common endpoint.Initial Side –It is also known as the reference line. All the measurements are done taking this line as the reference.Terminal Side-It is the side (or ray) up to which the angle measurement is done.To measure everything in this world, we need a unit in a similar angle measurement requires three units of measurement :
Draw angles using a protractor for the following measurements: 1. 45 degrees 2. 55 degrees 3. 70 degrees 4. 90 degrees 5. 130 degrees

Jun 15, 2021 · One commonly used system to measure angles is \index{angle ! degree}\index{degree measure}\textbf{degree measure}. Quantities measured in degrees are denoted by the familiar `$^{\circ}$' symbol. One complete revolution as shown below is \(360^{\circ}\), and parts of a revolution are measured proportionately.
Oct 6, 2021 · Probably the most familiar unit of angle measurement is the degree. One degree is \(\frac{1}{360}\) of a circular rotation, so a complete circular rotation contains 360 degrees. An angle measured in degrees should always include the unit “degrees” after the number, or include the degree symbol °. For example, 90 degrees = 90°.
Angles are formed when two lines intersect at a point. The measure of the 'opening' between these two rays is called an 'angle'. It is represented by the symbol ∠. Angles are usually measured in degrees and radians, which is a measure of circularity or rotation. Angles are a part of our day-to-day life. Engineers and architects use angles for ...

To convert from radian measure back to degrees, we multiply by the ratio 180 ∘ πradian. For example, − 5π 6 radians is equal to (− 5π 6 radians)(180 ∘ πradians) = − 150 ∘. 15 Of particular interest is the fact that an angle which measures 1 in radian measure is equal to 180 ∘ π ≈ 57.2958 ∘.
