1. The angle in the picture below is a(n) ....... [x] acute angle [ ] obtuse angle [ ] reflex angle [ ] right angle
Acute angles are less than 90o
2. The angle in the picture below is a(n) ....... [ ] acute angle [ ] obtuse angle [ ] reflex angle [x] right angle
Right angles are exactly 90o
3. The angle in the picture below is a(n) ....... [ ] acute angle [x] obtuse angle [ ] reflex angle [ ] right angle
Obtuse angles are between 90o and 180o
4. The angle in the picture below is a(n) ....... [ ] acute angle [ ] obtuse angle [x] reflex angle [ ] right angle
Reflex angles are between 180o and 360o
5. What is 'angle A' in the diagram below? [ ] 80o [ ] 100o [x] 120o [ ] 140o
The angles on a straight line add up to 180o
6. What is 'angle A' in the diagram below? [ ] 90o [ ] 180o [ ] 210o [x] 270o
The angles in a circle add up to 360o
7. What is 'angle A' in the diagram below? [ ] 55o [ ] 65o [x] 75o [ ] 85o
90o + 195o + 75o = 360o
8. What is 'angle A' in the equilateral triangle below? [ ] 50o [x] 60o [ ] 70o [ ] 80o
The angles in a triangle add up to 180o
9. What is 'angle A' in the regular pentagon below? [ ] 80o [ ] 88o [ ] 92o [x] 108o
All angles in a regular pentagon are the same. (The length of the sides are also the same)
10. What is 'angle A' in the regular hexagon below? [ ] 80o [x] 120o [ ] 180o [ ] 240o
Remember that all the angles in a regular hexagon are the same and all the lengths of the sides are the same
