An angle of 283 degrees is a reflex angle
It is a reflex angle of 283 degrees because it is greater than 180 degrees
Another measurement could be 283-360 or -77* or 283+360 or 643*
283 deg Centigrade = 541.4 deg Fahrenheit
283 kelvin = 49.73 degrees Fahrenheit [°F] = [K] × 9⁄5 − 459.67

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.
