Step 1:
I'll solve this step by step, carefully following the LaTeX formatting guidelines:

Step 2:
: Understand the definitions

- A quadrilateral is a four-sided polygon with four vertices and four angles - A rhombus is a quadrilateral with four equal sides

Step 3:
: Analyze the first statement "Every quadrilateral is a rhombus"

- This statement means ALL quadrilaterals must have four equal sides - Counterexample: A rectangle is a quadrilateral but not a rhombus - Therefore, this statement is FALSE

Step 4:
: Analyze the second statement "Every rhombus is a quadrilateral"

- A rhombus, by definition, has four sides and four vertices - This means a rhombus MUST be a quadrilateral - Therefore, this statement is TRUE

Final Answer

- First statement (Every quadrilateral is a rhombus): \boxed{\text{FALSE}} - Second statement (Every rhombus is a quadrilateral): \boxed{\text{TRUE}} Key Insight: Not all quadrilaterals have equal sides, but all rhombuses are four-sided polygons (quadrilaterals).
