    • Transformational geometry: successive enlargements, reflections, and rotations on a Cartesian plane
    • Mensuration of solids: surface area and volume of composite solids (conical frustum and hemisphere)
    • Kinematics and relative speed: non-uniform motion, overtaking, and meeting points of travelers
    • Statistics: frequency distributions, unequal class intervals, histograms, and sample mean age calculations
    • Circle geometry: cyclic quadrilaterals, tangents, chord properties, and angle subtensions
