Resumen del Recurso

Pregunta 1

Pregunta
How does the coordinate notation change when image is reflected across y-axis
Respuesta
  • (x, y) ----> (-x, y)
  • (x, y) ----> (x, -y)
  • (x, y) ----> (-x, -y)
  • (x, y) ----> (x, y)

Pregunta 2

Pregunta
There is only one type of transformations, and it is rigid transformation.
Respuesta
  • True
  • False

Pregunta 3

Pregunta
What are three kinds of rigid transformations?
Respuesta
  • Reflection
  • Dilation
  • Rotation
  • Translation

Pregunta 4

Pregunta
Rigid Transformation is a transformation of a figure that preserves size and shape. The three kinds of rigid transformations studied are translation (slide), reflection (flip), and rotation (turn).
Respuesta
  • True
  • False

Pregunta 5

Pregunta
Non-rigid transformations change the size but not the shape of the pre-image, dilation is not a non-rigid transformation
Respuesta
  • True
  • False

Pregunta 6

Pregunta
How does the coordinate notation change when point M (5, 0) is been reflected across x = 3
Respuesta
  • (x, y) ----> (5, 3)
  • (x, y) ----> (5, 6)
  • (x, y) ----> (3, 5)
  • (x, y) ----> (6, 5)

Pregunta 7

Pregunta
Which of the following transformations is a rotation? (There may be different answers)
Respuesta
  • (x, y) ----> (-x, -y)
  • (x, y) ----> (x, y)
  • (x, y) ----> (-x, y)
  • (x, y) ----> (-y, x)
  • (x, y) ----> (y, -x)
  • (x, y) ----> (-y, - y)

Pregunta 8

Pregunta
The reflection pre-image is always the same distance away from the line of reflection as the image.
Respuesta
  • True
  • False

Pregunta 9

Pregunta
What would be the coordinates to point "A" after a rotation of 180 degrees?
Respuesta
  • (2, -3)
  • (-2, 3)
  • (3, 2)
  • (-3, -2)

Pregunta 10

Pregunta
A rotation is a transformation which is also called a “turn”.
Respuesta
  • True
  • False
