Are we supposed to Learn the Transformation matrices..???

in gcse O-levels..

Yes... You just need to know how to make these matrices... Take 0,1 and 1,0 then rotate it or reflect it or do any of the transformation to get the resultant matrix... In case of the scale factor included put the scale factor for the line which is not invariant when you do the transformation on 0,1 and 1,0...

yes i need some detail guide on how to do this for all 6 transformations)..... plz help!

I don't know how to further explain it... Try getting that line (above) for every transformation yourself, that way you will remember it forever! Just keep all the transformation matrices in front of you... Then apply each transformation on (0,1) and (1,0) to get the required martix ... Do the reflection and rotation first...
