transformations, cross sections, cartesian planes, tessalations
If point A on a cartesian plane is at the coordinates (5,-4) and point b is a 90 degrees clockwise rotation around point C (0,0) where is point B?
(-4,-5)
If point A on a cartesian plane is at the coordinates (2,6) and point B is a 180 degree rotation around point c (0,0) where is point B?
(-2,-6)
If point A on a cartesian plane is at the coordinates (-6,5) and point B is a 90 degree anticlockwise rotation around point C (0,0) where is point b?
(-5,-6)
If point A on a cartesian plane is at the coordinates (3,-8) and point B is 3 units to the right and 4 units up then where is point B?
(4,11)
If point A is at coordinates (-2,-5) and point b is 5 unit up and 3 units to the right, then 6 units down where is point B?
(0,-6)
If point a on a cartesian plane is at coordinates (5,3) and point b is reflected on the x axis where is point B?
(5,-3)
If point A is on the coordinates (-4,-6) and point b is reflected on the y axis where is point b?
(4,-6)
What are the two directions that you can rotate?
anticlockwise, clockwise
If a cat falls from a tree, down to earth is it being translated?
yes
The basketball spins on a finger, without any particular direction is it being translated?
no
Is translation moving an object up, down, left or right
yes
how de we define rotation
turning a shape around a point
what is reflection
when the object is copied over from one side of the mirror line to the other
in maths we draw something called a mirror line. Anything on one side of the mirror line is copied over to the other side of the mirror line. What is this called
reflection
iF something is spinning, growing or shrinking is it still reflection
no, rfelection does not involve a change of size of the object or its shape
