Question

0.9 Classify the following angles as acute, obtuse, right, straight, zero, reflex or complete angles.
10; 135; 0; 130; 270 ; 180, 90, 250, 179.5;55°
​

Answer 1

Answer:

acute angles = 10,55

obtuse angles = 135,130,179.5

right angle = 90

zero angle= 0

reflex angle = 270, 250

complete angle = 180

Answer 2

Answer:

acute - 10,55

obtuse -135,130,179.5

right -90

straight - 180

zero - 0

reflex - 270,250

Step-by-step explanation:

acute angle is an angle whose measure is less than 90 and more than 0

obtuse angle is an angle whose measure is more than 90 and less than 180

right angle is an angle whose measure is exactly 90

straight angle is an angle whose measure is exactly 180

zero angle or null angle is an angle whose measure is 0

reflex angle is an angle whose measure is more than 180 and less than 360

complete angle is an angle whose measure is exactly 360
