MCQ Class 9 Maths Ganita Manjar Chapter 5 I’m Up and Down, and Round and Round Advertisement 1. Three collinear points can form: One circle Two circles Infinite circles No circleQuestion 1 of 202. Equal chords form equal: Radii Angles at centre Diameters TangentsQuestion 2 of 203. If central angles are equal, corresponding chords are: Equal Parallel Unequal TangentQuestion 3 of 204. The midpoint of a chord joined to centre forms: Acute angle Right angle Straight angle Reflex angleQuestion 4 of 205. Equal arcs subtend equal angles at: Centre Midpoint Diameter RadiusQuestion 5 of 206. In a cyclic quadrilateral, if one angle is 75°, opposite angle is: 75° 90° 105° 180°Question 6 of 207. If the angle at centre is 120°, angle at circumference is: 30° 60° 90° 120°Question 7 of 208. The distance from centre to a chord is measured along: Radius Diameter Perpendicular ArcQuestion 8 of 209. If two points are fixed, all possible centres lie on: Diameter Arc Perpendicular bisector RadiusQuestion 9 of 2010. The diameter divides the circle into: Four parts Two semicircles Three arcs One arcQuestion 10 of 2011. A semicircle is an arc of: 90° 120° 180° 360°Question 11 of 2012. The angle subtended by a diameter at centre is: 90° 180° 270° 360°Question 12 of 2013. A cyclic quadrilateral is always: Concyclic Parallel Equal-sided RegularQuestion 13 of 2014. If chord AB = chord CD, then their distances from centre are: Different Equal Double HalfQuestion 14 of 2015. If chord AB is longer than chord CD, then AB is: Farther from centre Closer to centre Equal distance Outside circleQuestion 15 of 2016. The angle subtended by an arc at any point outside the arc on circle is: Same Different Double ZeroQuestion 16 of 2017. The converse of cyclic quadrilateral theorem says if opposite angles sum to 180°, points are: Collinear Concyclic Parallel EqualQuestion 17 of 2018. Radius is always how much of diameter? Double Half Equal TripleQuestion 18 of 2019. The circle passing through triangle vertices is called: Incircle Circumcircle Semicircle SectorQuestion 19 of 2020. The study of chords and arcs mainly belongs to: Algebra Geometry Arithmetic StatisticsQuestion 20 of 20 Loading...
