How to Find a 122 Degree Angle

    • 1). Draw a straight line on a piece of paper along the baseline of the protractor, linking the "0" mark on the left to the "180" mark on the right. Make a small mark intersecting the straight line near the middle.

    • 2). Superimpose the protractor baseline on the line you drew. Adjust the position of the protractor until the center mark is directly over the intersecting mark on the line.

    • 3). Measure visually around the outer edge of the protractor, and locate the 122-degree mark. Draw a dot or a short line to identify it.

    • 4). Draw a straight line joining the 122-degree mark and the intersecting mark on the base line. The baseline and the 122-degree line form an angle of 122 degrees.

    • 5). Place the protractor over the angle just drawn. Align the protractor with the lines forming the angle. Check the outer edge of the protractor to confirm that your angle is exactly 122 degrees.
