Answer:
<u>A) The parallelograms all have congruent sides and angles. </u>
Step-by-step explanation:
<em>Remember,</em> a parallelogram in simple words is a flat shape (either a square, rectangle, or rhombus) that has four sides of equal length, and whose opposite angles are congruent.
In other words, Zach's blueprint using similar parallelograms would be chosen from either a square, a rectangle, or a rhombus, which all have congruent sides and angles.
