Describe a similarity transformation that maps trapezoid WXY

Describe a similarity transformation that maps trapezoid WXYZ to trapezoid PORS. Give the scale factor and name the type of dilation in your description. Similarity transformation: Type of dilation: Scale factor: Ay 4 6 4

Solution

Since WXYZ maps to PQRS.

Since PQRS is twice of WXYZ and reverse of it.

Hence scale factor = -2

Type of dilation is enlargement because a dilation that creates a larger image is called an enlargement.
