AC and BD are diagonals. ! Find the dimensions of the rectangle? ABCD is a rectangle [Given] ∴ BD = AC [Diagonals of a rectangle are congruent] ∴ BD = 8 cm [From (i)] BO = (1/2) BD [Diagonals of a rectangle bisect each other] Therefore, option (C) is the correct answer. Find the area of parallelogram ABCD. AD = 3 and AB = 10. 5. Since this is an "if and only if" proof, there are two things to prove. geometry. ABCD is a rectangle. AC = 3(x- 2) and BD =x+6 AC = BD = D %3D Diagonals of a rhombus are perpendicular. A. ABCD is a rectangle Fmd each length 1 BD 2CD 5 1n 3 AC 4AE l 5 i O KLMN Is a from MATH 101 at Huntington Beach High 1 AC BD 2 AD I BD 3 ACI BD 4 AC bisects ZBCD In ABC and DCB, AB = DC BC = BC AC = DB ABC DCB ABC = DCB Now, AB DC & BC is a transversal B + C= 180 B + B = 180 2 B = 180 B = "180 " /"2" = 90 So, ABCD is a parallelogram with one angle 90 ABCD is a rectangle. To Prove: Quadrilateral ABCD is a square. AC and BD are diagonals. 1. ABCD is a parallelogram with side AB=12 cm. Chapter-wise NCERT Solutions for Class 9 Maths Chapter 8 Quadrilaterals solved by Expert Teachers as per NCERT (CBSE) Book guidelines. Given AEC ∼ BED, which equation is true? Figure ABCD is a rectangle. Figure ABCD is a rectangle. Given: \(ABCD\) is a parallelogram with \(AB\) parallel to \(CD\) and \(AD\) parallel to \(BC\).Diagonal \(AC\) is congruent to diagonal \(BD\).. AC = 25 meters and BC = 15 meters. Let the rectangle be ABCD, We know that, Diagonals of rectangle are equal ∴ AC = BD ⇒ PQ = QR ∴ PQRS is a rhombus. Each diagonal of the square window measures 9 inches.
