Question

HELP!! I don't understand rotations at all and there are no good videos explaining it!
http://www.kutasoftware.com/FreeWorksheets/GeoWorksheets/12-Rotations.pdf
When it says at the origin, it means 0,0 right?
What am I supposed to do from there? How do I accurately place points?

Answer 1

yes, origin means 0, 0.
You should rotate the figure up to the required angle.

Answer 2

ok, for question 4. rotate 90 degrees clockwise about the origin
i'm 90 degrees is basically just sideways, but i don't know how to plot points

Answer 3

isn't the equation given ?

Answer 4

If you want to do it on your graph sheet simply use set squares (I hope you know what they are)...They are used for transferring forces , so just workout with the angle and there you go..

Answer 5

Oh god

Answer 6

I am fukken SCREWED!!
