obtuse angle
It is neither, a 180 degree angle is a straight angle. 90 degrees is a right angle. Angles between 90 and 180 degrees are obtuse. Angles over 180 degrees are reflex.
Reflex
A reflex angle is between 180˚ and 360˚. (An obtuse angle is between 90˚ and 180˚.)
An obtuse angle is greater than 90 but less than 180 degrees whereas other angles are acute angle, right angle or reflex angle.
No. An obtuse angle is one between 90 and 180 degrees. A reflex angle is one between 180 and 360 degrees.
A reflex angle is larger.
As "an angle that is obtuse or reflex".
Reflex: 180 < reflex < 360, obtuse: 90 < obtuse < 180, so difference (in whole numbers) can be as little as < 1o.
obtuse angle
A reflex angle which is between 180 and 360 degrees.
It is an obtuse angle. If it is between 90 degrees and 180 degrees it is obtuse but if it is over 180 it is reflex.
OBTUSE ; The word obtuse means 'blunt'. ACUTE ; is an angle between '0' and 90 degrees. The word 'acute' means sharp'. The third type of angle is REFLEX , which is an angle between 180 degrees and 360 degrees. The word 'reflex' means ' turned over' or 'turned aginst'. NB For any given point with two lines radiating from the point, the smaller angle can be either acute or obtuse, but the outside angle is always 'REFLEX'.
obtuse angle
They can make an obtuse angle, a straight angle or a reflex angle.
Obtuse.
A 172° angle is obtuse.
