-- A rhombus is always a parallelogram and a quadrilateral.
A rhombus can also be a square, but not all of them are.
-- A rectangle is always a parallelogram and a quadrilateral.
A rectangle can also be a square and a rhombus, but not all of them are.
-- A parallelogram is always a quadrilateral.
A parallelogram can also be a square, a rectangle, or a rhombus, but not all of them are.
-- A quadrilateral can be a square, a parallelogram, a rectangle, and a rhombus.

<em>However . . .</em>
-- You can definitely be sure that every square is always a quadrilateral,
a parallelogram, a rectangle, and a rhombus.
All four choices apply to a square, and should be selected.
Answer:
secθ = - 2
Step-by-step explanation:
Using the identity
sec²θ = 1 + tan²θ
= 1 + (
)² = 1 + 3 = 4 ( take the square root of both sides )
secθ = ± 
= ± 2
Since secθ < 0 in the third quadrant , then
secθ = - 2
