Two polygons are considered to be this when their side, vertex, and angle measurements are all identical.

What is congruent?

Analyze the following image. What is the line of reflection? 


x = -3

These are used to label a newly transformed shape.

What are primes?

A translation function is defined by the rule
(x, y) → (x + 2, y - 5). Which choice will be the image of the point (3,6) under this translation?

(5, 1)

The formula for a reflection over the line y = -x is as follows: (x, y) → (-y, -x). Point A's coordinates are (-2, 5), what is A' following a reflection over the line y = -x?

A' = (-5, 2)

200

The formula for a rotation 270º clockwise is as follows: (x, y) → (-y, x). Point A's coordinates are (6, -3), what is A' following a 270º clockwise rotation.

A' = (3, 6)

The point at (0,0) is called this.

What is the origin?

Which translation mapping is depicted in the graph?


(x, y) → (x - 6, y + 3)

ΔABC is reflected over line m.
Find x, y and z.

Rotate the following shape 90º counterclockwise. What are its new coordinates?

(x, y) → (-y, x)


Going clockwise starting at the top left vertex...(-3, -4), (1, 2), (6, -1), (2, -6)

Where is Crystal from?

What is New York/New Jersey?

This transformation produces similar shapes. It is the only transformation that produces an image that is incongruent to the pre-image.

What is dilation?

400

Conduct the following translation: (x, y) -> (x + 6, y - 5). Label the image appropriately.


TF will check coordinate plane for answer. All vertices of the image must be labeled with primes. The final coordinates are: A' (4, -2), B' (3, -4), C' (5, -4).

Analyze the following reflection. What line was this shape reflected over? What is the reflection formula?

The shape was reflected over the x-axis. The formula is (x,y) → (x, -y)

400

A rotation of 120º counterclockwise is the same as a rotation of ____º clockwise.

240º

Crystal's signature doodle/symbol (hint: think IP/Exit Slip comments).

What are smiley faces?

This is what we call a shape after it's been transformed.

What is image?

500

Conduct the following translation: (x, y) -> (x - 4, y - 3). Label the image appropriately and draw all translation vectors.


TF will check coordinate plane for answer. All vertices of the image must be labeled with primes and all vectors must have arrows that point towards the image. The final coordinates are: A' (-3, 4), B' (4, 4), C' (4, -1), D' (-3, -1).

500

Reflect shape A over the line y = 3. 


Final coordinates (going clockwise from the top left point): (2, 3), (4, 2), (4, 5), (2, 5).

What are the new coordinates of the following triangle: A (1, 3), B (5, 3), C (3, 7), after a 90º clockwise rotation [(x, y) → (y, -x)] about the center of rotation (3, 4).

(-2, -1)  (0, 3)  (2, -1)

(-1, 2)  (3, 0)   (-1, -2)

(2, 6)   (6, 4)  (2, 2)
