How to Draw 180 Degree Angle Using Compass

Using a compass to draw a 180-degree angle is a simple procedure. Here’s a detailed step by step process:

  • Draw a straight line: Use your ruler to draw a straight line on the paper. Name this line as AB.
  • Mark a Point: Anywhere between A and B, mark a point C.
  • Draw an Arc: Taking point C as the center, draw an arc with a compass of any radius. The arc should touch line AB and extend from point the left of point C to its right, or vice versa.
  • Name the Points: The straight line is cut by the arc twice. Name these points as P and Q.
  • Angle formed, i.e.  PCD angle is 180 degrees.

180 Degree Angle

180-degree angle is an angle formed when two lines or rays extend in opposing directions from a common point, producing a perfectly straight line. It is also called a straight angle.
