Geometry is a topic under Mathematics in the REET exam syllabus. Our database contains 5 questions from this topic across multiple REET papers.
Key facts from previous papers: True about triangles: (a) Isosceles has 2 equal angles (b) Sum of angles = 180° → (a) and (b) only. Match triangles: Equilateral-All sides equal, Isosceles-Two sides equal, Right-One angle 90°, Scalene-All different → a-II,b-I,c-IV,d-III. True about circles: (a) Equal chords equidistant from centre (b) Angle at centre = 2× angle at circumference (c) Same se → (a),(b),(c) only. Match angles: Acute <90°, Obtuse 90°-180°, Right=90°, Reflex 180°-360° → a-III,b-I,c-IV,d-II.
