This math topic focuses on identifying the types of angles: acute, obtuse, right, and straight. It allows students to practice recognizing angles by their degree measurements — acute being less than 90 degrees, obtuse greater than 90 degrees, right exactly 90 degrees, and straight exactly 180 degrees. Questions on the topic present images of different angles and ask students to classify them accordingly, providing options to select whether the given descriptions match the angles shown.
