reflection over the side RS
a translation of 10 units to the right
a rotation of 90' clockwise about vortex Q
a vertical stretch of scale factor 2 through contor C
a dilation of scale factor 1 through conter

Maggie claims that there are transformations that preserve the length of the rectangles sides Which of the following transformations could be used to support Ma class=

Respuesta :

Answer: B,D,E. Step-by-Step explanation

Transformation that preserve lengths are rigid transformation.

The options that support Maggie's claim are:

  • reflection over the side RS
  • a translation of 10 units to the right
  • a rotation of 90' clockwise about vortex Q  

All transformations are rigid transformation, except dilation.

Dilation are of two types

  • Stretch
  • Compress

Either of the two above, do not preserve length

This means that:

Options (d) and (e) will not preserve the lengths of the rectangle, because they represent dilation

Hence, the correct options that will preserve the length of the rectangle are: (a), (b) and (c)
