+shonella morgan No. You can use B and B prime as well. All you need is two lines in order to find the center of rotation. You can find the perpendicular bisector of AA'', BB' or CC'. They will all intersect at the center of rotation. All you have to do is choose ANY two of them.
Yes, I realised that practice is the key to mastering this topic. I have been pausing the video and practicing for this whole evening. I am getting there.
Oh my God!!!!!! YOU SAVED MY LIFE. I just could not understand Rotation and you saved me. Thank you very very very much.
Great. Good luck.
why not do a perpendicular bisector for b as well?
I think it would be better if we imagine /treat the centre of rotation as the origin, redefine the given points and find the other ones
Mr. David will you be putting up any practice activities on this topic? Hmmm this topic is overwhelming on my memory!
+shonella morgan I'm not sure if I will get a chance before the exam.
OK. Mr. David
Centre of rotation is (-2,-1)
I'm about to write CSEC 💖thank you so much
Good luck!!
Life Saver! Thank you.
Centre of rotation (-4,1)
Direction and Angle rotation
AA1= perpendicular bisector =:CC perpendicular bisector
thank you for the help :D also i like your voice
Glad I could help! lol...Thanks...just share the channel so others can benefit.
Are the numbers from the positive part when rotating anti-clockwise supposed to switch? like(1,4) when rotate gonna be (-1,4)??
Identical and congruent
90 degree centre of rotation
Wonderful video but can the students apply the formulas on CSEC?
This is a pretty old video of mine...I don't think I have any formulas in the rotation video
Am clueless
270 degree Anticlockwise
I understand
Mr. David is it only A Aprime and C Cprime that the perpendicular lines can be drawn?

Ok. I have been trying to practice for the whole of today.
Rotation of 90 clockwise
Object and image
Afternoon sir
THANKS SO MUCH SIR
Excuse me sir, how would you know when to move clockwise or anti-clockwise?
If they ask you to perform a rotation they will tell you whether clockwise or anticlockwise.
90 clockwise
Rotation

+shonella morgan This type of question requires some practice in order to get it.
