CIRCLE BASIC CONCEPTS BASICS OF CIRCLES GEOMETRY FOR BEGINNERS CIRCLES FOR SSC CGL COMPETITIVE EXAMS In all these videos on Circles from class 9th chapter 10 I have always focused on explaining the basics and then solving the questions. My way of solving question will always refer back to the basics explained previously so that students can make the connect between basics and application of them. Lets now start about the Circles from class 9th chapter 10: Circles is one of the longest chapters in 9th Math syllabus however most interesting and important as well. We will focus and understand very deeply into the basics first and then move into solving each and every question from the chapter exercises from NCERT and RS Agarwal both. In Basics we will be covering the following: What is a circle Its Radius and Diameter Its Periphery Chord Secant Lines Tangent Concentric Circle Arc Degree measure of arc Congruent arc Minor Major Arc Minor Major or Alternate segment Sector Quadrant Congruent circle Cyclic Quadrilateral Then we will be covering almost all the theorems: Equal arcs of a circle subtend equal angles at the center Equal arcs of a circle produces equal chords Perpendicular from the Centre of the circle to the chord bisect the chord. Equal length chords will be equidistant from the centre of the circle. Longer the chord nearer to the centre From three non collinear points one and only one triangle can be drawn. The angle made by an arc of a circle at the centre is double the angle subtended by it at any point on the remaining part of the circle. The angle in the semicircle is a right angle Angles in the same segment are equal The sum of the either pair of the opposite angles of a cyclic quadrilateral is 180 If one side of the cyclic quad. is produced then the exterior angle is equal to the opposite interior angle Please use this link for the YouTube playlist of Circle Class 9th: This link will get you 87 videos Probability Class 9 NCERT Solutions Statistics Class 9 NCERT Solution Class 9 - Geometry - Number System - Algebra Practice Questions Probability Class 10 NCERT Solutions Quadrilaterals Class 9 NCERT CBSE Solutions Triangles Class 9 NCERT CBSE Solutions Surface Areas and Volumes Class 9 Herons Formula Class 9 NCERT CBSE Solutions Circle Class 9 NCERT CBSE Solutions Areas of Parallelograms and Triangles Class 9 Lines and Angles Class 9 Linear Equations in Two Variables Class 9 Coordinate Geometry Class 9 Polynomials Class 9 Number Systems Class 9 Mathsphy provides unconventional and a better way of learning maths.
