Select all of the sequences of transformations that will preserve distance.

• rotate 180∘ clockwise about the origin, reflect across the x-axis

• dilate by a factor of 0.75 centered at the origin, reflect across the y-axis

• rotate 180∘ clockwise about the origin, translate 2 down and 5 to the right

• translate 7 up and 7 to the right, dilate by a factor of 7 centered at the origin

• rotate 90∘ counterclockwise about the origin, dilate by a factor of 1 centered at the origin

Given a sequence of transformations that include a reflection across the x-axis and a dilation centered at the origin by a scale factor of 9, does the sequence of transformations preserve the distances between the vertices?

Select all of the sequences of transformations that will result in the triangles being mapped onto each other.
