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