The Selina Concise Maths Solutions for Class 9 present a firm platform for students to prepare as many questions as possible and refer to the right answers. Show that F is the mid-point of BC. [Angle sum property of a quadrilateral] ⇒ 30x = 360°. R is the mid point of DC and S is the mid point of DA. These Punjab boards are Gujranwala Board, Lahore Board, Faisalabad Board, Multan Board, Rawalpindi Board, Bahawalpur Board Sargodha Board, DG … Quadrilaterals will typically be of standard shapes with four sides like rectangle, square, trapezoid, and kite or irregular and uncharacterized shapes. ⇒ AD = BE and BE = CF (Opposite sides of a parallelogram are equal), Also, AD || BE and BE || CF (Opposite sides of a parallelogram are parallel). 3. The Length of the other Diagonal is: Let ABCD be a quadrilateral and its diagonals AC and BD bisect each other at right angle at O. and ∠ADC+∠BCD = 180° (co-interior angles). We are very thankful to him for providing these notes. Chapter 09: First Order Differential Equations Notes of the book Mathematical Method written by S.M. A line is drawn through E parallel to AB intersecting BC at F (see Fig. Show that if the diagonals of a quadrilateral bisect each other at right angles, then it is a rhombus. So, they will bisect each other. To show that, ABCD is a rectangle if the diagonals of a parallelogram are equal. The first exercise has 12 questions and second exercise has 7 questions. NCERT solutions have been prepared in a logical and simple language. (i) ∠DAC = ∠DCA (AC bisects ∠A as well as ∠C), ⇒ AD = CD (Sides opposite to equal angles of a triangle are equal), also, CD = AB (Opposite sides of a rectangle), ⇒ ∠CDB = ∠CBD (Angles opposite to equal sides are equal), also, ∠CDB = ∠ABD (Alternate interior angles). (i) quadrilateral ABED is a parallelogram, (ii) quadrilateral BEFC is a parallelogram, (iv) quadrilateral ACFD is a parallelogram. Mathematics 9 is written by Dr. Karamat H. Dar and Prof. Irfan-ul-Haq and this book is published by Carvan Book House, Lahore, Pakistan. Solutions of all the chapters are given below. Q and R are mid points of side BC and CD respectively. Diagonal AC of a parallelogram ABCD bisects ∠A (see Fig. DS = BQ (Halves of the opposite sides of the rhombus), ∠SDR = ∠QBP (Opposite angles of the rhombus), DR = BP (Halves of the opposite sides of the rhombus), RC = PA (Halves of the opposite sides of the rhombus), ∠RCQ = ∠PAS (Opposite angles of the rhombus), CQ = AS (Halves of the opposite sides of the rhombus). F is mid point of side DC and FP || CQ (as AF || EC). 6. Class 9 built a foundation for Class 10 as well as higher studies. Logarithm 3.

If the diagonals of a parallelogram are equal, then show that it is a rectangle. 10. All the solutions are done properly considering the latest CBSE Syllabus 2020-21. 8.21). To Construct: Draw a line through C parallel to DA intersecting AB produced at E. (i) CE = AD (Opposite sides of a parallelogram), ∠A+∠CBE = 180° (Angles on the same side of transversal and ∠CBE = ∠CEB), (ii) ∠A+∠D = ∠B+∠C = 180° (Angles on the same side of transversal). As in quadrilateral PQRS one pair of opposite sides is equal and parallel to each other, so, it is a parallelogram. i.e., we have to prove that ABCD is parallelogram and AB = BC = CD = AD, ∠AOB = ∠COB (Opposite sides of a parallelogram are equal). P and S are the mid points of AD and AB respectively. NCERT Solutions for Class 9 Maths Chapter 8 contains two exercises. Yusuf, A. Majeed and M. Amin, published by Ilmi Kitab Khana, Lahore - PAKISTAN. Show that: AD = BC (Opposite sides of a parallelogram), AB = CD (Opposite sides of a parallelogram). Find all the angles of the quadrilateral. Thus by mid point theorem, SR || AC and SR = ½ AC. Other boards other than Punjab do not follow class 9 math notes. Ch8-Linear Graphs and Their Inequalities 9th Class Math PDF Notes Chapter 8 Linear Graphs and Their Applications Mathematics Notes as per Federal Board / Pindi Board and other Punjab Boards Syllabus. The angles of quadrilateral are in the ratio 3 : 5 : 9 : 13. MCQs from CBSE Class 9 Maths Chapter 8: Quadrilaterals AB = CD (Opposite sides of parallelogram ABCD), ⇒ AE = FC (E and F are midpoints of side AB and CD), AECF is a parallelogram (AE and CF are parallel and equal to each other), AF || EC (Opposite sides of a parallelogram).
