Angles can be either straight, right, acute or obtuse. An angle is a fraction of a circle where the whole circle is 360°. A straight angle is the same as half the circle and is 180° whereas a right angle is a quarter of a circle and is 90°
Acute has the word cute in it and small things can be cute so to remember a small angle/ acute angle use that trick. Obtuse sounds big so it is a big angle
