Fred had to create a series of transformations to a triangle for a project. He decided his first

transformation will be translating 4 units to the left and 1 unit up. Which rule describes the translation

that was applied to Fred’s triangle?

• (x, y) → (x – 1, y + 4)

• (x, y) → (x + 4, y − 1)

• (x, y) → (x + 1, y + 4)

• (x, y) → (x – 4, y + 1)

Which best explains the transformation?

• (x, y) → (x, y)

• (x, y) → (−x, −y)

• (x, y) → (x, −y)

• (x, y) → (−x, y)

John ordered an Uber take him and his friends to the movies. When looking at the map he saw his

ride was located at (3, 2). The Uber will need to translate to his current location of (−1, 5), which of

the following describes the translation?

• (x, y) → (−1/3x, 5/2y)

• (x, y) → (x − 4, y + 3)

• (x, y) → (x − 3, y + 4)

• (x, y) → (x − 2, y + 5)

Which best describes this transformation?

• A translation 3 units up and 3 units to the right.

• A translation 3 units down and 3 units to the left.

• A dilation that is a reduction with a scale factor of 3 centered at the origin.

• A dilation that is an enlargement with a scale factor of 3 centered at the origin.

Which rule best represents this dilation?

• 
• 
• 
• 

Which statement must be true?

• If k is greater than 1, the image of the polygon is congruent to the polygon.

• If k is between 0 and 1, the image of the polygon is smaller than the polygon.

• If k is greater than 1, the image of the polygon is smaller than the polygon.

• If k is between 0 and 1, the image of the polygon is congruent to the polygon.

The first clue was to reflect the quadrilateral

across the y–axis. In which quadrant is the image

of the quadrilateral located?

• I

• II

• III

• IV

What is the measure of angle 4?

• 63

• 95

• 117

• 148

What is the measure of ANGLE A ?

• 90

• 12

• 130

• 50
