This math topic focuses on identifying types of angles. Students are prompted to determine whether the given angles are acute (less than 90°), obtuse (greater than 90°), right (exactly 90°), or straight (exactly 180°). Each question presents an angle in image form with options to select whether it matches the described angle type, enhancing the understanding of angle classifications in geometry basics.
