A 45 degree angle is known as an acute angle

Level 5-6 Shapes - Angles

Can you tell an acute angle from an obtuse angle? Do you know how many degrees there are in a circle or in a triangle? Are you familiar with the angles of a regular pentagon or a regular hexagon?

Play this quiz to gain an acute knowledge of angles.

Which of these options do you prefer?

  1. The angle in the picture below is a(n) .......
    1 - Acute angles are less than 90o
  2. The angle in the picture below is a(n) .......
    4 - Right angles are exactly 90o
  3. The angle in the picture below is a(n) .......
    2 - Obtuse angles are between 90o and 180o
  4. The angle in the picture below is a(n) .......
    3 - Reflex angles are between 180o and 360o
  5. What is 'angle A' in the diagram below?
    3 - The angles on a straight line add up to 180o
  6. What is 'angle A' in the diagram below?
    4 - The angles in a circle add up to 360o
  7. What is 'angle A' in the diagram below?
    3 - 90o + 195o + 75o = 360o
  8. What is 'angle A' in the equilateral triangle below?
    2 - The angles in a triangle add up to 180o
  9. What is 'angle A' in the regular pentagon below?
    4 - 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?
    2 - Just like the regular pentagon in question 9, remember that all the angles in a regular hexagon are the same and all the lengths of the sides are the same
