180 is double 90
180 degrees
180 degrees a half of a revolution is a semi circle protractor
From 180 degrees to 90 degrees based on my protractor... :D
No it is a semi circle. Something like a protractor
180 degrees
To measure a reflex angle of 283 degrees with a protractor, first, position the protractor so that the vertex of the angle aligns with the midpoint of the protractor. Since a reflex angle exceeds 180 degrees, measure the smaller angle formed by the two lines, which will be 77 degrees (360 - 283 = 77). Then, count clockwise from the 180-degree mark to the 283-degree mark on the protractor to confirm the measurement visually.
To measure a reflex angle using a 180-degree protractor, first position the protractor so that its baseline aligns with one side of the angle, ensuring the center point is at the vertex. Measure the smaller angle formed on the protractor, which will be less than 180 degrees. Subtract this measurement from 360 degrees to find the reflex angle. For example, if the smaller angle measures 120 degrees, the reflex angle would be 360 - 120 = 240 degrees.
Yes, you can measure 20 degrees on a protractor. A protractor typically has degree markings ranging from 0 to 180 degrees and sometimes up to 360 degrees. To measure 20 degrees, align the protractor's baseline with one side of the angle, then find the 20-degree mark on the curved edge. Ensure the center point of the protractor is at the vertex of the angle for an accurate measurement.

Because the 3 interior angles of any triangle add up to 180 degrees.
A protractor is typically used to measure angles in degrees. It consists of a semicircular or circular scale marked from 0 to 180 degrees (or 0 to 360 degrees in a full protractor). Some protractors also include measurements in radians, but the degree is the most common unit. The accuracy of angle measurement can vary based on the protractor's design and quality.
Using a protractor you'll find that the 3 angles of any triangle add up to 180 degrees
