    Theorem: The perpendicular from the centre of a circle to a chord bisects the chord.



    Given: A circle with centre O. AC is a chord and OB ⊥ AC.

    To prove: AB = BC.

    Construction: Join OA and OC.

    Proof: In triangles OBA and OBC,

    ∠OBA = ∠OBC = 90o (Since OB ⊥ AC)

    OA = OC (Radii of the same circle)

    OB = OB (Common side)

    ΔOBA ≅ ΔOBC (By RHS congruence rule)

    ⇒ AB = BC (Corresponding sides of congruent triangles)

    Thus, OB bisects the chord AC.

    Hence, the theorem is proved.

    Let ΔABP and a parallelogram ABCD be on the same base AB and between the same parallels AB and PC. To Prove : ar( ΔPAB ) = (1/2)ar( ABCD) Draw BQ ||AP to obtain another parallelogram.ABQP and ABCD are on the same base AB and between the same parallels AB and PC. There fore, ar(ABQP) = ar(ABCD) But ΔPAB ≅ ΔBQP( Diagonals PB divides parallelogram ABQP into two congruent triangles. So ar (PAB) = ar(BQP) -----------(2) ∴ ar (PAB) = (1/2)ar(ABQP) -----------------(3) [ from (2)] This gives ar (PAB) = (1/2)ar(ABCD) [ from (1) and (3)]

    ABCD is a rectangle and P, Q, R and S are the mid-points of the sides AB, BC, CD and DA respectively. Show that the quadrilateral PQRS is a rhombus.

    Sol:   In a rectangle ABCD, P is the mid-point of AB, Q is the mid-point of BC, R is the mid-point of CD, S is the mid-point of DA AC is the diagonal.

                 

                 From (1) and (2), we get

                                           PQ = SR and PQ || SR

                 Similarly, by joining BD, we have

                                           PS = QR and PS || QR

                 i.e. Both pairs of opposite sides of quadrilateral PQRS are equal and parallel.

                 ∴ PQRS is a parallelogram.

                 Now, in ΔPAS and ΔPBQ,

                 

                 ∴Their corresponding parts are equal.

                    ⇒

    PS = PQ

     

                    Also

    PS = QR

    [Proved]

                    and

    PQ = SR

    [Proved]

     

    PQ = QR = RS = SP

     

                 i.e. PQRS is a parallelogram having all of its sides equal.

                 ⇒PQRS is a rhombus.

    Ram Kushwah 1 day, 14 hours ago

    diameter =d = 35 cm
    Radius= r = 17.5 cm
    Circumference of semi circle = πr
    = (22/7) x 17.5
    = 77 cm

    so the circumference of base of cone
    2πR = 77
    R = 77 x (7/44)
    R = 12.25 cm

    The radius of semi circular sheet = slant height of conical cup
    which is
     l = 17.5 cm
    As,
    R2 + h2 = l2

    12.25*12.25 + h2 = 17.5*17.5

    150.0625+ h2=306.25

    h2=156..1875

    h=12.49
