Question

In the given figure ac and bd are diagonals of kite abcd with ab= ad while ag and me are diagonals of rectangle aegm.if ad =dg and bg is a line segment then x-y=

Answer 1

We know that ABCD is a kite

So, AB=AD and BC=CD.

And EFGH are mid points of AB ,BC,CD,AD

Now in order to prove that  EFGH is a rectangle

We will first of all construct this:

join AC and BD.

In ΔABD  the E and F are mid points.

so we can write this as:

EF ║BD

EF = 1/2 BD    (this will be an equation 1) (here will be using the mid point theorem)

In Δ BCD

G and H are mid points.

Which means GH║ BD

GH=1/2 BD  (this will be an equation 2)

From the equation (1) and (2)

We can easily see that

EF║ GH

and

EF = GH ( these are the opposite sides of quadrilateral

EFGH is a parallelogram)

We know that  ABCD is a kite so the diagonal intersect at 90.

So ∠AOd= 90

90 is the final answer for this question.
