**How do you draw a 20 degree angle science.answers.com**

A digital protractor must have its scale "zeroed" before it can accurately read an angle. To work properly, the digital protractor first must have its scale "zeroed." Put the arms of the protractor together and press them tightly against a flat work surface.... It is hard to get an accurate angle even with a protractor. Old time woodworkers traditionally did not have protractors so they used the ratio of two unit values to set an angle. They just remembered the ratios for the angles they used the most. It is easy to set an angle with a carpenter square. The angle set in the photos is 20°. I know this because the table included with this Instructable

You can use a protractor to measure an angle by identifying the vertex, or center point, of the angle, placing the origin/center-point of the protractor over the vertex, lining up the bottom edge with one of the angle edges, and locating the measurement of the angle.

## How To Draw A 20 Degree Angle With A Protractor

### 90 degree angle= 1⁄4 of a circle 180 degree angle = 1⁄2 of a circle Use the straight edge of the protractor to draw a straight line. This line will form one side of your angle. Find the center hole on the straight edge of the protractor. Place the hole over one end point of the line you have drawn. Line up the zero on the straight edge of the protractor with the line. Make a mark at

- 12/10/2018 · Find the degree of the angle you wish to draw on the protractor's appropriate scale. Align your reference line with the protractor's baseline and mark the paper at the degree of measurement. If you are drawing an acute angle (less than 90 degrees), use the scale with the smaller numbers.
- Mark this point on the line as point D. Angle CDB is exactly one third of angle CAB, or 20 degrees. Check it with the protractor. Check it with the protractor. Construct a line perpendicular to line AB and passing through line D. Start by drawing a circle centered on point D and then two larger circles centered on the points where the first circle intersects line AB.
- You can use a protractor to measure an angle by identifying the vertex, or center point, of the angle, placing the origin/center-point of the protractor over the vertex, lining up the bottom edge with one of the angle edges, and locating the measurement of the angle.
- For example, if you counted 20° from the dotted line, the reflex angle measures 180 + 20 which is 200°. This is how you can use a protractor to measure as well as draw angles, quickly and easily. Make good use of this guide and score good grades in geometry.
