PYQ Practice Set 1
Twenty-nine coordinate-geometry questions from real SSC papers, with the paper named after each one. Nearly half (14) are from CGL 2025, the year this topic became a regular Tier 1 question; the rest are from CHSL and Selection Post, which ask the same types, plus one CGL 2022 Tier 2 question. Quick ones (a midpoint, an intercept, which point lies on a line) sit next to two-step ones such as an altitude's slope from three vertices or the area of a plot from its corners, so read whether the question wants the slope, the perpendicular slope or the full equation before you choose. The last question is from Tier 2; allow about 20 minutes for the set.
