what does rotation mean?
To turn
How do you reflect?
line y= x
Line x=y
what are the two ways to dilate?
to multiply or to divide
whats the angles that measures more than 90o?

what's the rule for (x-7,y5)
7units to the left, 5units up.
if were to rotate a triangle 90 degrees clockwise, what direction would that be?
Right

If were to change the size of a pentagon by scale factor 3, would the shape become bigger or smaller?
Bigger
a scalene triangle which angle adds up to less than 90o. what do you call angles that add up to less than 90o.
acute angles
write this as a rule
(x -12, y0)
12 units to the left, the origin.
find the incorrect one: 90=1 turn 180=2 turn 450=5 turn 360=4turn 540=6 turn 270=3turn 630=9 turn 720=8 turn
630=7turn
what line was this image reflected on?
The X-axis
solve the equation: if 3,6 was enlarge by scale factor 4 what's the new numbers?
12, 24
If a square has 4 right angles, how many degrees does it add up to?
90*4= 360
