Question

two quadrilaterals are shown, where quadrilateral efgh is created by reflecting quadrilateral abcd across a line and then rotating it. what is the value of x, in units?

Explanation:

Step1: Identify congruent sides

Since quadrilateral EFGH is created by reflecting and rotating quadrilateral ABCD, they are congruent. Side BC in quadrilateral ABCD corresponds to side GF in quadrilateral EFGH.

Step2: Determine the value of x

We know that BC = 4. So, x = 4.

Answer:

4
