Answer 1

Hey there!

The pairs

1) Straight angle = Half of a revolution

2) Right angle = One fourth of a revolution

3) Acute angle = Less than one fourth of a revolution

4) Obtuse angle = Between 1/2 and 1/4 of a revolution.

5) Reflex angle = more than half of a revolution

6) Complete angle = One complete revolution

hope helped!

Answer 2

Hey there !!!!!

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

One revolution = 360°

(i)Straight angle=180°=half of a revolution

(ii)Right angle=90°=One-fourth of a revolution

(iii)Acute angle= less than 90° = less than One-fourth of a revolution

(iv)Obtuse angle=greater than 90° and lesser than 180°= between 1/4 and 1/2 of a revolution

(v)Reflex angle= Greater than 180°=More than half of a revolution

(vi)One complete revolution=360°
