Level 1

This math topic focuses on classifying triangles based on the measurements of their angles. It involves identifying whether a triangle is acute (all angles less than 90°), right (one angle exactly 90°), or obtuse (one angle more than 90°). Through the problems presented, students must match the given name of a triangle to its corresponding angle description, reinforcing their understanding of triangle classification. This topic is part of a larger unit on triangle classification within geometry.
