exploded diper , here u go...
Remember, this method is applicable to ALL transformations. All you need is, two points and there result under that specific transformation.
and if A makes A' under transformation X, then the second point you choose, B, must also make B' under transformation X.

i hope this helps you guys

*Adding*
And the transformation abcd can be found by multpliying the inverse of the matrix representing the Given points by the matrix of the Image points
(ie.)
(-1 -4) * (1 4)^-1
(3 2) (3 2)


Amazing work Amd

i wanted to ask if anyone knows how to prepare or what to prepare for english speaking test since i am a private candidate ?!

(iv)
CD = CE + ED
ED= 1/2 of OE
= 1/2 (c+a)
CD = a+ 1/2(c+a)
= (2a +a +c )/2
=1/2 ( 3a +c)
(c) both of them are parallel
CD is half of OB
hope dat helps

b)
(iv)
CD = -OC + OD

OD = OE + ED

OE : ED = 2 : 1 (given)
OE/ED = 2/1
OE/2 = ED = 0.5 OE

OD = OE + ED
OD = OE + 0.5 OE
OD = 1.5 OE

CD = -OC + 1.5 OE
put the value of OE, whatever u got in b(iii), and value of OC and u'll get ur answer In Shaa Allah
got that?

 

[exploded diper]

explain 3 (b)....

 

[queen of the legend]

here is the vectors question answer

 

[***amd***]

View attachment 38839here is the vectors question answer

c) as we see the 2 lines CD and OB have a ratio between them i.e. 1:2
because 1/2 * x = CD and x = OB
where x = 3a + c
thus due to this ratio we conclude the two lines are parallel AND in the same direction.

but if we had CD = -1/2 * x , then the 2 lines would have been parallel BUT in opposite direction.
am i clear?

how to get 2013 papers

you have to take x common

[exploded diper]

for the first part(i)a the s.f should be -2 because the image is double the size and negative because the image is behind p not infront it
for the second part (i)b you should join every vertex of triangle "P" where it belongs to triangle "q" after it had enlarged and the point where the three lines join should be the center of enlagment
for(ii) number 2 was a k which means any number when the matrix which has this k surrounding by two ones on the top right so it is a shear x-axis invariant and the k is the scale factor

ans also (iii) (b)..........
