Answer:

<em><u>A:</u></em>

<em><u>Square</u></em>

<em><u>Rectangle</u></em>

<em><u>Parallelogram</u></em>

<em><u>Quadrilateral</u></em>

<em><u>Rhombus</u></em>

<em><u></u></em>

<em><u></u></em>

Step-by-step explanation:

All sides and angles are equal so it is a square

All angles are 90 degrees so it is a rectangle (eliminate C)

Opposing angles and side lengths are congruent so it is a parallelogram (eliminate D)

It has 4 sides so it is a quadrilateral (eliminate B)

Since all of the other answers are eliminated you don't necessarily need to prove that is is a rhombus, but it is good practice.

Opposing sides are congruent so it is a rhombus.
