This math topic focuses on identifying different types of angles: acute (less than 90 degrees), obtuse (greater than 90 degrees), right (equal to 90 degrees), and straight (equal to 180 degrees). Students analyze images of angles and determine their type through multiple-choice questions, enhancing their understanding of angle classification within basic geometry.
