ABCD is a rhombus and P, Q, R, S are mid-points of AB, BC, CD and DA respectively. Prove thatquadrilateral PQRS is a rectangle. |
|
Answer» Answer: Given- ABCD is a rhombus and P, Q, R and S are the mid-points of the sides AB, BC, CD and DA respectively. To Prove-PQRS is a rectangle Construction, AC and BD are joined. Proof, In ΔDRS and ΔBPQ, 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) THUS, ΔDRS ≅ ΔBPQ by SAS congruence condition. RS = PQ by CPCT --- (i) In ΔQCR and ΔSAP, 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) Thus, ΔQCR ≅ ΔSAP by SAS congruence condition. RQ = SP by CPCT --- (ii) Now, In ΔCDB, R and Q are the mid points of CD and BC respectively. ⇒ QR || BD ALSO, P and S are the mid points of AD and AB respectively. ⇒ PS || BD ⇒ QR || PS Thus, PQRS is a parallelogram. also, ∠PQR = 90° Now, In PQRS, RS = PQ and RQ = SP from (i) and (ii) ∠Q = 90° Thus, PQRS is a rectangle. |

(5) If both the pair of opposite angles of a quadrilateral are congruent then it isparallelogram. |
|
Answer» Answer: There are five ways in which you can prove that a quadrilateral is a parallelogram. The FIRST four are the converses of parallelogram PROPERTIES (including the definition of a parallelogram). Make sure you remember the oddball fifth one — which isn’t the converse of a property — because it often comes in handy: If both pairs of opposite sides of a quadrilateral are parallel, then it’s a parallelogram (reverse of the definition). If both pairs of opposite sides of a quadrilateral are congruent, then it’s a parallelogram (converse of a property). Tip: To get a feel for why this proof method works, take two toothpicks and two pens or pencils of the same length and put them all TOGETHER tip-to-tip; create a closed figure, with the toothpicks opposite each other. The only shape you can make is a parallelogram. If both pairs of opposite angles of a quadrilateral are congruent, then it’s a parallelogram (converse of a property). If the diagonals of a quadrilateral bisect each other, then it’s a parallelogram (converse of a property). Tip: Take, say, a pencil and a toothpick (or two pens or pencils of different lengths) and make them cross each other at their midpoints. No matter how you change the angle they make, their tips FORM a parallelogram. If one pair of opposite sides of a quadrilateral are both parallel and congruent, then it’s a parallelogram (NEITHER the reverse of the definition nor the converse of a property). Tip: Take two pens or pencils of the same length, holding one in each hand. If you keep them parallel, no matter how you move them around, you can see that their four ends form a parallelogram.

rk fabricators has got a order for making a frame for machine of their client. for which, they are using a autocad software to create a constructible model that includes the relevant information such as dimensions of the frame and materials needed. the frame will have a solid base and will be cut out of a piece of steel the final area of the frame should be 54 sq m. the digram of frame is shown below. in order to input the right values in the autocad software, the engineer needs to calculate some basic things. on the basis of the above information, answer any four of the following questions: (i) what are the dimensions of the outer frame ? (a) 10 + x and 5 + x (b) 10 - x and 5 - x (c) 10 + 2x and 5 + 2x (d) 10 - 2x and 5 – 2x(ii)a metal sheet of minimum area is used to make the frame. what should be the minimum area of metal sheet before cutting ? (a) 4x2 + 30x +50 (b) x2+ 27x +55 (c) 5x2+30 (d) 4x2 + 50 (iii)what is the area of required final metal frame ? (a) 4x2 + 30x +50 m2 (b) x2+ 27x +55 m2 (c) 4x2+50x m2 (d) 4x2 + 30 m2 (iv) if the area of the frame is 54 sq m, what is the value of x ? (a) 0.75 m (b) 3.0 m (c) 1.5 m (d) 1.8 m (v) what is the perimeter of the frame? (a) 36 m (b) 42 m (c) 45 m (d) 39 m |
|
Answer» Given : final area of the FRAME should be 54 sq m Inner rectangle dimensions are l-10 b-5. Outer is x meters from all sides To Find : dimensions of the outer frame Area of frame Value of x Perimeter of frame Solution: dimensions of the outer frame 10 + x + x and 5 + x + x = 10 + 2x and 5 + 2x Correct option is : c) (10 +2x) and (5 + 2x) Area of frame = (10 +2x)(5 + 2x) = 50 + 20x + 10x + 4x² = 4x² + 30x + 50 area of required final METAL frame = 4x² + 30x + 50 - ( 10 * 5) = 4x² + 30x 4x² + 30x = 54 => 2x² +15X = 27 => 2x² +15x - 27 = 0 => 2x² + 18x - 3x - 27 = 0 => 2x(x + 9) - 3(x + 9) = 0 => (2x - 3)(x + 9) = 0 => x = 3/2 x = - 9 ( x can not be negative ) Hence x = 1.5 m Perimeter of frame : 2(10 + 2x + 5 + 2x) = 30 + 8x =30 + 8(1.5) = 42 m Learn More: The outer length and breadth of a photo frame is 60 cm × 40 cm.If . fabricators has got a order for making a frame |
