Angle, Symmetry & Transformation
MTH 319a
To run the tutorials simply click on the video you wish to play remembering to pause the video when attempting the questions! You should work through the exercises and homework in a squared jotter to keep all your work together. You should mark every section as soon as you finish it and write down your score.
For certain areas you will need a scientific calculator like the casio fx-85GT PLUS.
Once you have practiced the skills, be sure to see if you can apply them in the Applications questions at the bottom of the page. These questions should be revisited every so often as it is important to revise previous work so you don't forget it. Good luck! :)
Bronze Level
Symmetry should be something you have seen before from 2nd Level Maths. This bronze module revises one line of symmetry and shows you how to reflect a picture in a line of symmetry.
