Sub: Maths
Classify the following angles as acute, Right, obtuse, straight and reflex angles.
30°,40°,120°,90°,180°,650,225°,1650,300°,170°,2150,315°,75°,
340º,170°
​

Answer 1

any angle under 90 degrees is acute. A right angle is 90 degrees always, and obtuse angles are always above 90 degrees. Straight angles are always 180 degrees. A reflex angle is more than 180 degrees but less than 360 degrees. Hope this helps.
