Two way stretch? That's new. Is that in the syllabus even?

 

[princess Anu]

Enlargement main scale factor same hota hai. Jab values differenet hoti hain it means it's stretch.

konsi values? is main bhi toh scale factor same lag raha hai :S?

Qs 7 part aii?

Take area of walls, not ceiling etc. You'll get the answer, it's simple.

 

[princess Anu]

first wid factor 2 y inv line then factor 3 x axis inv line

can u tell me the method you use to identify or differentiate between stretch/ two way stretch and enlargement?

Wall ke area hi ley hai lekin answer ghalat a raha hai. Can you show me the solution please?

Stretch:
To describe a stretch, state;
i. the stretch factor, p
ii. the invariant line,
iii. the direction of the stretch
(always perpendicular to the invariant line)
Scale factor =

d) Enlargement:
To describe an enlargement, state;
i. The scale factor, K
ii. The centre of enlargement (the invariant point)
Scale factor =
lengthof the object
lengthof the image
>> Enlargement by the scale factor --- centre ------
If K > 0, both the object and the image lie on the same side of the centre of enlargement.
If K < 0, the object and the image lie on opposite side of the centre of enlargement.
If the scale factor lies between 0 and 1, then the resulting image is smaller than the object.
[although the image is smaller than the object, the transformation is still known as an
enlargement

Area of image = K2 area of object

Hey I discovered something
If you just change the number you can see random sketches
The id is not unique for sketches but ordered
