CONIC SECTION The sections of the double napped right circular cone with the plane are called conic sections. eg:- circle, ellipse, parabola and hyperbola etc. all are the examples of conic sections. APPLICATIONS:- These curves have wide applications in the field of planetary motion, design of telescope, antenas, reflectors of flash light and automobile headlights. Vertex of the double napped cone separate the cone into two parts each part is called Nappes. α (alpha) is the angle made by the generator with the x-axis. Maths Conic Section Part 1 Class 11 NCERT-cbse mathematics DIFFERENT TYPES OF CONIC SECTIONS:- CIRCLE:-   When β(beta) = 90, then intersection of cone with plane is called circle. ELLIPSE:- When α<β<90 then intersection of plane and cone gives an ellipse. PARABOLA:- When α= β then intersection of plane and cone gives parabola. HYPERBOLA:- When 0<β<α then the intersection of plane and cone gives a hyperbola. Maths Conic

  Theorems on Parallelograms Ch-8 Class-IX Explanation of all theorems on Parallelograms chapter 8 class IX, Theorem 8.1, 8.2, 8.3, 8.4, 8.5, 8.6, 8.7, 8.8, 8.9, 8.10, Mid point theorem and its converse. All theorems of chapter 8 class IX. Theorem 8.1: Prove that a diagonal of a parallelogram divides it into two congruent triangles. Given: In Parallelogram ABCD, AC is the diagonal To Prove:  △ACD ≌ △ABC Proof: In △ACD and △ABC,  ∠1 = ∠2  .........   (Alternate angles ∠3 = ∠4  ..........  (Alternate interior angles AC = AC ........   (Common Sides ⇒ By ASA  ≌ rule   △ACD ≌ △ABC   Theorem 8.2: In a parallelogram, opposite sides are equal. Given: ABCD is a parallelogram To Prove : AB = CD and BC = AD Proof:  In △ ACD and △ ABC,  ∠ 1 = ∠ 2  .........   (Alternate angles ∠ 3 = ∠ 4  ..........  (Alternate interior angles AC = AC ........   (Common Sides ⇒ By ASA  ≌ rule   △ ACD ≌ △ ABC ⇒ AB = CD and BC = AD  …..  By CPCT Theorem
