Translation
What is translation?
A translation is moving up or down.
What is rotation?
A rotation means, when you rotate something one point will always stay the same (in the same place.)
What is dilation?
Dilation is changing the size of a figure.
What is a hypotenuse line?
A hypotenuse line is the line that is not touching the right angle. It is directly across from the right angle.
What is reflection?
Reflection is when an image is reflected across a line. Creating a mirror image.
The four types of direction in a translation are?
Up, Down, Right, Left.
what does it mean if the rotating coordinate, (X,Y) change to its opposite?
The Coordinates are rotating 180 degrees.
find the new coordinates of ( 6, -3) if the scale factor is 2.
The new coordinates would be (12, -6).
What is a leg line?
The leg line is the line that is touching the right angle.
If you create a reflection of a person you are?
Taking a picture of them.
Find the new coordinate of (-2) if you slide right 4 points.
The new coordinate would be ( 2).
What is the largest turn that can be made in a rotation?
180 degrees
360 degrees
90 degrees
The largest turn that can be made is 360 degrees. ( full turn)
If the original coordinates are (2,2) and you decrease the scale factor 1/2 what would the coordinates now be?
The coordinates would now be (1,1)
What is a real life job that requires the pythagorean theorem.
Cooking
Architecture
Journalism
Architecture
What is the line separating the pre- mage from the image?
The axis of reflection.
Find the new coordinates of (7) if you move right 2 spaces.
The new coordinate would be (9)
What is the smallest type of turn that can be made in rotations?
45 degrees
90 degrees
180 degrees
The smallest type of turn is 90 degrees. (quarter turn)
Ashley had a poster made of her dog. If the poster is 8 times the size of the original picture, and the height is 120 what was the height originally?
10cm
15cm
12cm
The original poster was 15cm in height.
What is the correct equation for a hypotenuse line?
a2 + b2 = c2 =
c2 + b2 = a2 =
a2 + c2 = b2 =
a2 + b2 = c2 =
When the line is on the (y axis) we change (x, y) into what?
(x, -y)
(-x, y)
We change it into ( -x, y)
What is the rule from a point (5, 3), translating to (-5, -3)
The rule is (X - 10, Y - 6)
If A (2,5) triangle is rotated 90 degrees counter clockwise, what is A?

a2 + c2 = b2 =
c2 + b2 = a2 =
When the line is on the (x axis) we change (x, y) into (x, -y)
(-x, y)
you change it into (-x, y).
