Geometry - Shape Classification (2D) - Advanced

This math unit begins by introducing students to the basics of polygon classification, first by the number of sides and then by the regularity or irregularity of their shapes. It progresses into more specific properties of circles, reinforcing the relationship between diameter and radius through practical problems. As the unit advances, students further explore the geometry of quadrilaterals, identifying specific types like kites and rhombuses based on visual properties. Subsequently, the unit shifts focus to angles, starting with the classification of angles as acute, obtuse, right, or straight, and then moving to exact angle measures such as 90, 180, or 270 degrees. This foundation supports the next part of the unit, which delves into triangle classification by angles, providing various exercises to identify triangle types based on angle measurements. The unit then builds on this by introducing classification of triangles based on side lengths, distinguishing between isosceles, scalene, and other types of triangles. The progression culminates in a deeper understanding of how to analyze and categorize shapes based on both angles and side lengths, providing a comprehensive geometry unit.
