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'.
An angle of between 90 degrees and 180 degrees is called an obtuse angle, an angle that is exactly 180 degrees is called a straight angle (because it creates a straight line), and an angle of more then 180 degrees is called a reflex angle.
That is an obtuse angle.
It is called an obtuse angle. ■
It is called a reflex angle.
An angle which measures between 180 and 360 degrees is called a reflex angle.
An angle of between 90 degrees and 180 degrees is called an obtuse angle, an angle that is exactly 180 degrees is called a straight angle (because it creates a straight line), and an angle of more then 180 degrees is called a reflex angle.
A reflex angle is between 180˚ and 360˚. (An obtuse angle is between 90˚ and 180˚.)
An angle that is between 90 degrees and 180 degrees is called an obtuse angle. Ex. : 175 degrees, 140 degrees.
An acute angle is between 0 and 90 degrees. Angles between 90 and 180 degrees are called obtuse angles.
An angle greater than 180 degrees but less than 360 degrees is a reflex angle.
That is an obtuse angle.
It is called an obtuse angle. ■
An angle greater than 90 but less than 180 degrees is an obtuse angle
It is a reflex angle of 225 degrees
It is called a reflex angle.
Angles that are 180 degrees (θ = 180°) are known as straight angles. • Angles between 180 and 360 degrees (180°< θ < 360°) are called reflex angles.
An angle which measures between 180 and 360 degrees is called a reflex angle.
