A. A right angle
B. Acute angle
C. Obtuse
D. Acute angle
Explanation: An acute is any angle between 0-89 degrees. 0>90(It’s smaller than 90degress )
A right angle is at exactly 90degrees.
An obtuse angle is any angle greater than 90 degree but less than 180. So from 91-179 degrees
Straight line angle is an angle exactly at 180
A reflex angle is any angle greater than 180 and less than 360 . Any angle from 181-359 degrees
A full angle is an angle exactly at 360.
Hope this makes sense. Study this and remember it’ll help you a lot in geometry.
