3. Show that the figure formed by joining the midpoints of sides of a rhombus successivelyis a rectangle. |
|
Answer» Given AC,BD are diagonals of a quadrilateral ABCD are perpendicular. P,Q,R and S are the mid points of AB,BC, CD and AD respectively. Proof:In ΔABC, P and Q are mid points of AB and BC respectively. ∴ PQ|| AC and PQ = ½AC ..................(1) (Mid point theorem) Similarly in ΔACD, R and S are mid points of sides CD and AD respectively. ∴ SR||AC and SR = ½AC ...............(2) (Mid point theorem) From (1) and (2), we get PQ||SR and PQ = SR Hence, PQRS is parallelogram ( pair of opposite sides is parallel and equal)Now, RS || AC and QR || BD.Also, AC ⊥ BD (Given)∴RS ⊥ QR. Thus, PQRS is a rectangle. |

all squares are parallelograms?? true /false |
|
Answer» It is true as:- Aparallelogramis a four-sided figure with two sets of parallel sides. This is always true.Squaresare quadrilaterals with 4 congruent sides and 4 right angles, and they also have two sets of parallel sides. Sincesquaresmust be quadrilaterals with two sets of parallel sides, thenall squares are parallelograms. |

IF A={Parallelogram} B={square,rectangle,rhombus, trapezium}then B-A |
|
Answer» A rectangle is a parallelogram with equal angles.A parallelogram with sides of equal length is called a rhombus.A rectangle with sides of equal length is called a square. A trapezium is a quadrilateral having onlyone pairof opposite sides parallel.But a parallelogram is a quadrilateral havingboth pairsof opposite sides parallel.So, a trapezium cannot be a parallelogram. Therefore B - A = { trapezium} |

Answer» A(2,3) ------------------P(4,m)--------------B(6,-3) Applying section formula , Let λ is the ratio by which P divides the line joining A and B.x = (λx₂ + x₁)/(λ + 1) here , x = 4 , x₁ = 2 , x₂ = 6 Now, 4 = (6λ + 2)/(λ + 1)4(λ + 1) = 6λ + 2 4λ + 4 = 6λ + 2 2 = 2λ ⇒ λ = 1 Hence, p divides the line AB into 1 : 1 ratio. Now, for y - co - ordinate y = (λy₂ + y₁)/(λ + 1) m = (1 × -3 + 3)/(1 + 1) = 0Hence , m = 0 |

g) If the vertical angle of an isoscles triangle is 110° what must be size of each of its base angles ?---- |
|
Answer» We know that an isosceles triangle has two sides of the same length and one side of different length. The sum of the measures of the angles of the triangle is 180°. We know the vertical angle of the triangle i.e., We know the vertical angle of the triangle i.e., 110 Let the base angles be x and x since they have the same value.x+x+110= 1802x= 70x= 35,35base angles 35° and 35° |
