Sure, I'd be happy to check your work! Let's go through each question:

1) Every rhombus is a parallelogram.
Your answer: True
Correct!

2) Every parallelogram is a rectangle.
Your answer: False
Correct! A parallelogram can have angles that are not 90 degrees, whereas a rectangle must have all angles equal to 90 degrees.

3) Every rectangle is a square.
Your answer: False
Correct! A rectangle can have sides of different lengths, whereas a square has all sides equal.

4) Every square is a rectangle.
Your answer: True
Correct! A square has all angles equal to 90 degrees, making it a rectangle.

5) Every square is a rhombus.
Your answer: True
Correct! A square has all sides equal, making it a rhombus.

6) The opposite angles of a parallelogram are always equal.
Your answer: True
Correct! In a parallelogram, opposite angles are congruent (or equal) to each other.

7) What is the sum of all the angles in a quadrilateral?
Your answer: 360 degrees
Correct! The sum of all angles in a quadrilateral is always 360 degrees.

8) What is the sum of adjacent angles in a parallelogram?
Your answer: 180 degrees
Correct! Adjacent angles in a parallelogram are supplementary, meaning they add up to 180 degrees.

Great job! You answered all the questions correctly.
