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.
No. Trapezoids are not parallelograms at all.
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.
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 !
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.
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).
Yes, all Squares are rectangles, but not all rectangles are squares because it needs to have all equal sides.
Yes, all rectangles are parallelograms. However, not all parallelograms are rectangles.
It is NOT as case of 'Some'. It is ALL rectangles are parallelograms.
No but all squares are a rectangles
All rectangles are quadrilaterals.
No. Only some parallelograms are rectangles. But all rectangles are parallelograms.
All squares are rectangles also, but not all rectangles are squares, only equilateral rectangles are considered square.
