(1) 30°
(2) 91°
(3) 179°
(4) 90°
(5) 181°
(6) 360°
(7) 128°
(8) ( 90.5 )°
(9) ( 38.3 )°
(10) 80°
(11) 0°
(12) 15°
​

Answer 1

Answer:

(i) Acute angle

This is because its measure is less than 90° but more than 0°.

(ii) Obtuse angle

This is because its measure is more than 90° but less than 180°

(iii) Obtuse angle

This is because its measure is more than 90° but less than 180°.

(iv)Right angle

This is because its measure is 90°.

(v) Reflex angle

This is because its measure is more than 180° but less than 360°.

(vi) Complete angle

This is because its measure is 360°.

(vii) Obtuse angle

This is because its measure is more than 90° but less than 180°.

(viii) Obtuse angle

This is because its measure is more than 90° but less than 180°.

(ix) Acute angle

This is because its measure is more than 0° but less than 90°.

(x) Acute angle

This is because its measure is more than 0° but less than 90°.

(xi) Zero angle

This is because its measure is zero.

(xii) Acute angle

This is because its measure is more than 0° but less than 90°.
