Geometry

Geometry for SSC CGL Tier 1 and Tier 2: lines and angles, quadrilaterals and polygons, triangles and congruence, Pythagoras, the centres of a triangle with inradius and circumradius, similar triangles and proportionality, and circles (chords, angles, cyclic quadrilaterals, tangents and common tangents), with diagrams throughout. After the six topic sections come quick methods for angle chases and circle lengths, worked questions, three practice sets, two sets of real SSC geometry questions from 2022 to 2025 and a 15-minute test.
