Some paralleograms are rectangles. A right paralleogram is a rectangle. In the case of a rectangle, all angles formed by the sides are right angles and opposite sides are parallel. The sum of adjacent angles in a parallelogram is 180 degrees.

Are all trapezoids paralleograms?
No. Trapezoids are not parallelograms at all.
Can the diagonals of a parallelogram be the same length?
Yes, but only when the shape is a rectangle (or square). Other paralleograms will have one diagonal longer than the other. And yes, rectangles and squares ARE parallelograms.
Can two paralleograms with different shapes have the same area?
Definitely. You can pick an area, and there are an infinite number of parallelograms, including an infinite number of rhombuses and an infinite number of rectangles, all with different shapes, that all have that same area. But there's only 1 square, and only 1 circle !
What are false statements about quadrilaterals?
Probably the main one is that all quadrilaterals are rectangles. This isn't true- they can be paralleograms and trapezoids. A quadrilateral just means that something had four sides. So anything that adds to that, or takes away from it, is therefore false.
what is the lateral faces of a rectangular prism?
They are all rectangles (or 2 squares and 4 rectangles).They are all rectangles (or 2 squares and 4 rectangles).They are all rectangles (or 2 squares and 4 rectangles).They are all rectangles (or 2 squares and 4 rectangles).
Are all squares rectangles but not all rectangles squares?
Yes, all Squares are rectangles, but not all rectangles are squares because it needs to have all equal sides.
Are all rectangles parallelagrams?
Yes, all rectangles are parallelograms. However, not all parallelograms are rectangles.
Are all rectangles quadrilites?
All rectangles are quadrilaterals.
All rectangles are squares?
No but all squares are a rectangles
Are some parallelograms rectangles?
In fact, some are rectangles, but not all are.
Are all parrellelograms rectangles?
No. Only some parallelograms are rectangles. But all rectangles are parallelograms.
Why are some rectangles squares?
All squares are rectangles also, but not all rectangles are squares, only equilateral rectangles are considered square.
