This math topic focuses on understanding and identifying the number of lines of symmetry in different 2D shapes such as hexagons, triangles, and pentagons. Students will determine and select the correct count of lines of symmetry from a set of options for each shape presented. These exercises are part of an introductory unit on shape classification in geometry.
