answer with step-by-step explanation:

a. wx is perpendicular to xy - true:

(since x is adjacent to x and y and all angles are 90 degrees in a square, therefore wx is perpendicular to xy)

b. ∠w is congruent to ∠x - true:

(all angles in a square are equal to each other)

c. ∠w is supplementary to ∠x - true:

(∠w and ∠x both are right angles which add up to 180 degrees so they are supplementary angles)

d. wxyz is a rhombus - true:

(a rhombus has all sides equal in length and so has a square so it is a rhombus)

e. wxyz is a trapezoid - false:

(a trapezoid has only one pair of parallel sides while a square has two pairs of parallel sides)

f. wx is parallel to yz - true:

(wx and yz are parallel to each other)
