Are all cubes rectangles?
No because cubes do not have opposite sides that are different lengths. Cubes have all equal sides and all equal coners. A cube is not a rectangle.
Which statements about squares and rectangles are true?
The statements:It is a quadrilateral (a shape with 4 sides)It has two pairs of opposite sides equal of equal length which are parallelAll angles are equal at 90°The diagonals are equal in length and bisectall squares are rectangles but not all rectangles are squaresare all true about squares and rectangles
Are all rhombuses also rectangles?
No. Rhombuses that are also rectangles are called squares. Rhombuses are parallelograms with 4 equal sides, while rectangles are parallelograms where all the angles are right.
Are all rectangles parallelagrams?
Yes, all rectangles are parallelograms. However, not all parallelograms are rectangles.
What is a rectangle but not a parallelogram?
A parallelogram has two pairs of opposite sides that are equal in length and parallel. A rectangle has two pairs of opposite sides that are equal in length and are parallel. Thus all rectangles are parallelograms. (A rectangle has the extra condition that all its angles are equal at 90°, thus all parallelograms are not rectangles.) There cannot be a rectangle that is not a parallelogram.
