reflex Angle
A reflex angle is an angle that measures greater than 180 degrees and less than 360 degrees. It is formed by extending one of the sides of an angle beyond 180 degrees.
A reflex angle is an angle greater than 180 degrees but less than 360 degrees. It is formed when the arms of an angle are on the opposite sides of a line, creating a "bow" shape. In other words, a reflex angle is the extension of an angle beyond 180 degrees.
To measure a reflex angle, place the protractor on the vertex (the point where the two arms of the angle intersect) and align the baseline of the protractor with one of the arms. Then, locate the other arm and observe the scale on the protractor to determine the measurement of the reflex angle.
Remember, a complete angle is equal to 360 degrees. Therefore, a reflex angle can be found by subtracting the measurement of the angle from 360 degrees. For example, if you have an angle measuring 240 degrees, the reflex angle would be 360 degrees - 240 degrees = 120 degrees.
