This math topic focuses on the classification of triangles based on their angles. It includes problems where students must identify and select images of triangles categorized by the following angle types: acute (all angles less than 90 degrees), obtuse (one angle more than 90 degrees), and right (one right angle). Each question provides a description of the type of triangle and multiple images as possible answers, from which the correct one needs to be chosen based on the triangle's angle properties. This is part of a broader practice unit on geometry, specifically triangle classification.
