how do you measure reflex angles?
To measure a reflex angle, you will need a protractor. Here's how you can do it:
1. Place the protractor on a flat surface, ensuring that the center of the protractor's base line coincides with the vertex (the point where the two arms of the angle meet) of the reflex angle you want to measure.
2. Align one of the arms of the reflex angle with the baseline of the protractor. Make sure that the other arm of the angle is on the opposite side of the protractor.
3. Look at the protractor's scale, which is divided into 360 degrees, with 0 degrees on the right side and 180 degrees on the left side.
4. Locate the arm of the reflex angle that falls on the protractor's scale. Determine the degree measure of the angle by reading the number on the scale that aligns with the other arm of the angle.
5. Reflex angles are greater than 180 degrees, so regardless of the reading you obtain from the protractor, subtract it from 360 to get the actual measurement of the reflex angle.
Note: Make sure to position the protractor accurately and read the angles correctly to get an accurate measurement.
