What is 90 Degree by Reflex?
The term "90 degree by reflex" refers to an angle measurement that is greater than 90 degrees but less than 180 degrees. In simpler terms, it describes an angle that has been extended beyond a right angle (90 degrees) but has not yet reached a straight angle (180 degrees). This type of angle is crucial in various geometric calculations and plays a significant role in polygonal shapes and other geometric figures.
How is 90 Degree by Reflex Calculated?
Calculating angles, including "90 degree by reflex," requires a basic understanding of angle measurement. Here’s a simple way to calculate it:
- Identify the vertex of the angle.
- Measure the angle formed between the two rays extending from the vertex.
- To find the reflex angle, subtract the acute angle from 360 degrees.
For example, if the acute angle measures 120 degrees, the reflex angle would be calculated as follows:
360 degrees - 120 degrees = 240 degrees. Thus, the "90 degree by reflex" angle in this case is indeed the reflex angle, which is essential to understand in various geometric applications.
