Which special quadrilateral is both a rectangle and a rhombus? Explain how you know Thanks
a square
Because a square has four 90-degree angles and, when turned on an angle, the angles opposite each other are all equal (the top angle is the same as the bottom angle, and the same for the left and right). This makes a square a rectangle.

The special quadrilateral that is both a rectangle and a rhombus is called a square. A square is defined as a quadrilateral with all sides equal in length and all interior angles equal to 90 degrees. This meets the criteria for both a rectangle (since it has 90-degree angles) and a rhombus (since it has all sides equal). Therefore, a square is both a rectangle and a rhombus.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- A parallelogram has sides A, B, C, and D. Sides A and B have a length of #7 # and sides C and D have a length of # 9 #. If the angle between sides A and C is #(3 pi)/8 #, what is the area of the parallelogram?
- Two opposite sides of a parallelogram each have a length of #12 #. If one corner of the parallelogram has an angle of #( pi)/3 # and the parallelogram's area is #48 #, how long are the other two sides?
- A parallelogram has sides with lengths of #16 # and #8 #. If the parallelogram's area is #80 #, what is the length of its longest diagonal?
- Two opposite sides of a parallelogram each have a length of #2 #. If one corner of the parallelogram has an angle of #(7 pi)/8 # and the parallelogram's area is #5 #, how long are the other two sides?
