In Euclidean geometry, every rectangle is also a parallelogram.
A rectangle is a parallelogram, but a parallelogram is not necessarily a rectangle. This is because a parallelogram can be so many other things, like a rhombus or a square.
That depends on the rectangle. If it is a square, then yes, it is also a rhombus. Otherwise, it would be a parallelogram.
No. Most parallelograms are not rectangles. But every rectangle is a parallelogram.
A rectangle is a four-sided shape, a parallelogram. Since a rhombus is a parallelogram then it is also a rectangle in a sense. Along with a square, it is a type of rectangle.
A parallelogram is also a square, rhombus, and rectangle.
A rectangle is a type of quadrilateral, and it also is a parallelogram.
Because the area of a parallelogram is length times perpendicular height and the area of a rectangle is also length times perpendicular height
That would be a rhombus. (It can't be a 'square', because a square is also a rectangle.)
When all 4 corners are right angles. A parallelogram has two pairs of parallel sides. A rectangle has two pairs of parallel sides; therefore a rectangle is a parallelogram. A rectangle also has four 90° angles; a parallelogram does not necessarily have four 90° angles, therefore a parallelogram may, or may not, be a rectangle.
All rectangles are also parallelograms. A parallelogram needs four 90-degree angles to be a rectangle
