<reasoning>

Analyze the geometric markings on the parallelogram

\[

$$\begin{aligned} &\text{Tick marks on all four sides} \implies \text{four congruent sides} \implies \text{Rhombus} \\ &\text{Right angle symbol in one corner} \implies \text{four right angles} \implies \text{Rectangle} \end{aligned}$$

\]

Determine the specific classification

\[

$$\begin{aligned} &\text{Rhombus} \cap \text{Rectangle} = \text{Square} \\ &\text{Four congruent sides and four right angles} \implies \text{Square} \end{aligned}$$

\]
</reasoning>

<answer>
The parallelogram is a <blank>square</blank> because it has <blank>four congruent sides and four right angles</blank>.
