Question

Quadrilateral A'B'C'D' is a reflection of Quadrilateral ABCD over the y-axis What is the length of C'D'​

Answer 1

4 units

Explanation:

a reflection is a rigid transformation, meaning that the size and shape of the figure does not change. therefore, the length of C'D' will be the same as the length of CD.

Length of CD: 4 units

so,

C'D'=4units

Answer 2

C'D' = 4

Explanation:

When the figure is reflected, the length of the segments does not change.

CD = 4 so C'D' = 4
