Explanation:

Angles and their names

  • An angle greater than 90° is an obtuse angle
  • An angle less than 90° is an acute angle
  • An angle equal to 90° is a right angle
  • An angle equal to 180° is a straight angle
  • An angle equal to 360° is a complete or whole angle.

In part a, we have an angle greater than 90°, so it's an obtuse angle

In part b, we have an angle less than 90°, so it's an acute angle

In part c, we have an angle less than 90°, so it's an acute angle
