Dear Students,
We're going to do two steps between today and Monday in our chapter on Reflection
Step 1 : Ex. 9 (A) : Nos. 8, 9, 10, 11, 12, 13
Yesterday we did an introduction to reflection. We found the coordinates of a point under reflection in the X-axis, Y-axis and the Origin. You worked this out with the help of plotting these points and their reflections on a graph. I hope that you could also note the cooridnates of a point under reflection without drawing the graph ! (But, when in doubt, draw a rough graph and note the point - the important thing is not to make a mistake !).
In this first step for today, we are given the coordinates of the reflection of a point and we have to find the coordinates of the original point ! This is the reverse of the wok we did yesterday ! Remember that the point itself is noted by a capital letter and its reflection is that same letter with a small dash in the right hand top of the alphabet. Please use this technique so that you do not get mixed up with the point and its reflection !
So, all the best ! use graph paper or draw a graph and plot the points and find the answer !
Step 2 : Ex.9 (A) : Nos. 14, 16, 17, 18, 19
I trust that while the above work takes care and time, it is fairly straightforward. Your friends with whom I am doing this work with in school have covered this step too and are finding it smooth sailing.
In the sums for this step - we are asked either to

I trust that while the above work takes care and time, it is fairly straightforward. Your friends with whom I am doing this work with in school have covered this step too and are finding it smooth sailing.
In the sums for this step - we are asked either to
- find the reflection of a point and then find the reflection of that reflection ! thus we have e.g. the point A and then A with one dash and then A with two dashes ! OR
- you are given the reflection of a point and then you are asked to find the original point and then the reflection of that point.
Plot all the points on a graph and show the written work !
Remember, if you have any difficulty, I am just an e-mail away at broelmiranda@gmail.com !
