In the given figure, AC and BD are the diagonals of
kite ABCD with AB = AD while AG and ME are the
diagonals of rectangle AEGM. If AD = DG and BG
is a line segment, then x – y equals
a. 21
b. 48
c. 42
d. 68
Answers
b) 48 degree is the right answer
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.
