180 Diploma Angle

The 180-degree angle is a straight angle because it kinds a straight line. It’s precisely half of the total angle (360-degree angle). If we discuss a real-life instance of a 180-degree angle, then an ideal instance is the angle between the 2 palms of a clock at 6 o’clock. The angle between the 2 palms of the clock is 180° as a result of it kinds a straight line.

A 180-degree angle is a straight angle and it’s precisely half of a revolution. It’s also known as a half-circle angle. A straight angle is produced by a straight line. The 2 arms of the angle that are making 180-degree are simply reverse to one another from the frequent vertex. A 180-degree angle modifies the path of some extent. 90-degree angle is half of 180-degree angle and it is called a proper angle. Have a look at the picture given under exhibits how a 180-degree angle seems. 180 degree angle

Within the above picture, rays AO and OB share a typical level O. AO and OB rays are reverse to one another. AB is a straight line and forming an angle of 180 levels.

An angle that measures 180 levels is known as a straight angle. At any time when we assemble a 180-degree angle, it at all times kinds a straight line, that’s the reason it is called a straight angle. There are completely different names for angles of various measurements. For instance, half of a 180-degree angle, i.e a 90-degree angle is called a proper angle in geometry. Equally, double of 180 levels, that’s 360-degree angle is called a whole angle. Angles which might be lower than 180 levels are categorized as acute and obtuse angles.

Two angles that collectively type 180 levels are generally known as supplementary angles. Whereas two or extra angles combining collectively at some extent on a line forming 180 levels are generally known as linear pairs of angles.

The 180-degree angle may be drawn with the assistance of a protractor and compass.

Establishing 180-Diploma Angle Utilizing a Protractor

Comply with the given steps to assemble a 180-degree angle with the assistance of a protractor:

  • Step 1: Draw a ray OA.
  • Step 2: Place the protractor at level O.
  • Step 3: Within the internal circle of the protractor, search for 180° studying and with a pencil mark a dot and identify it C.
  • Step 4: Be part of O and C. Now, ∠AOC=180 diploma angle.

Comply with the given steps to assemble a 180-degree angle with the assistance of a compass.

  • Step 1: Draw a straight line with assist of a ruler and identify it AB.
  • Step 2: Mark some extent O wherever between A and B.
  • Step 3: Take O as a middle level, draw an arc of any radius with assist of a compass, the arc ought to be from the left of level O to the suitable of O, or vice-versa, touching the road AB.
  • Step 4: The arc cuts the straight line at two factors. Mark the cuts as factors C and D.
  • Step 5: Thus, the angle COD is 180 levels angle.


Essential Notes

  • The 180-degree angle can also be known as a straight angle, half-circle, or semi-circle.
  • A 180-degree angle may be constructed with a protractor or a compass.
