Dilation
What is the scale factor of dilation?
The dilation is an enlargement and a scale factor of three.
What is a reflection?
a geometric transformation resulting in a mirror image.
What is a rotation?
It is the number of degrees by which a figure is rotated about the origin.
What is a translation?
The displacement of a figure or a shape from one place to another
What is an acute angle?
It's any angle less than 90 degrees
The figure before a transformation has occurred.
Is reflecting over the Y-axis up or down or left or right.
Its left or right
What happens when a point is rotated 90 degrees counterclockwise?
it changes the positions of ( x,y)
when doing a translation why do your new labels have a ' ( example - A'B'C')
It shows that it isn't the original shape.
Whats an obtuse angle?
An obtuse angle is greater than 90 and less than 180 degrees
Is dilation an enlargement or reduction?
Both
Is reflecting over the x-axis left or right or up or down.
Its up or down
What happens when a point is rotated 90 degrees clockwize?
A rotation of 90 clockwise changes the point and (x, y) becomes (y, -x).
When translating a figure, how do you figure out how many units you need to slide up or down
count up the variables and make sure they are the same meaning C would go with C'
What is a straight angle?
An angle that is exactly 180 degrees
How do you do dilation?
Multiply both coordinates by the scale factor
What would reflection about the X-axis do too (x , y)
it would make ( x , -y)
Its too the right
does translation go up, down , slide or turn.
What is a right angle
A right angle is exactly 90 degrees
how do you dilate 2
multiplying the x and y value of each point by 2
What would reflection too the y axis does too ( x, y)
it becomes ( -x , y)
Is rotating your figure counter clockwise left or right
Its too the left
How do you do translation?
You change the x and y coordinates.
What is a reflex angle?
A reflex angle is more than 180 degrees
