Unit 1, Lesson 1 - 4 Review

Identify the transformation from ABC to A'B'C'.

• 90^o clockwise rotation
• 90^o counter clockwise rotation
• Reflection across the y-axis
• Reflection across the x-axis

a transformation that changes the size of a figure, but not the shape

• translation
• rotation
• reflection
• dilation

Identify the transformation from ABCD to A'B'C'D'.

• Translation
• Reflection across the x-axis
• Reflection across the y-axis
• 90^o counter clockwise rotation

What does a translation do to an image?

• Turns it 90* clockwise
• Mirrors it
• Shrinks it
• Slides it

Which rule would result in a reflection in the x-axis?

• (x, y) → (2x, 2y)
• x, y) → (x + 4, y + 4)
• (x, y) → (y, -x)
• (x, y) → (x, -y)

What type of transformation is quadrilateral PQRS?

• Translation 4 units right
• Rotation around the origin
• Reflection over the x-axis
• Reflection over the y-axis

What transformation is happening to the red triangle to get to the blue triangle?

• Translation
• Rotation
• Reflection
• Dilation

Determine where T' would be if you translated T three units to the right and six units up.

• (5, 1)
• (2, -5)
• (-1, 1)
• (8, -2)

Determine where X' would be if you translated X three units to the left and nine units down.

• (-4, 4)
• (-10, 2)
• (-4, -5)
• (-1, 5)

Triangle ABC is going to be translated. How is ABC being translated if the rule (x,y) --> (x+3, y-2) is used?

• 3 up and 2 left
• 3 right and 2 down
• 3 left and 2 up
• 3 right and 2 up
