What else can I help you with?
All rhombuses are rectangles?
No. A rectangle has all angles equal to 90o; a rhombus has opposite angles equal but they do not need to be 90o; thus all rhombuses are not rectangles. All rectangles have four equal angles and opposite sides of equal length, all four sides need not be the same length; a rhombus has all 4 sides of equal length; thus all rectangles are not rhombuses either.
What are the types of parallelogram?
A parallelogram has opposite sides parallel and equal in length, and opposite angles are equal. Squares, rectangles and rhombuses are all parallelograms.
Is a sqare always a rectangle?
no, but a square is always a rectangle. You see, squares have 4 equal sides. Rectangles don't HAVE to have 4 equal sides, but one side is equal to the opposite. So, all squares are rectangles, but not are rectangles are squares.
What is a plain figure in which all of the angles are right angles opposite sides are parallel and opposite sides are equal?
rectangles squares
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 opposite sides of all quadrilateral are in equal length?
no, only parallelograms (rectangles, squares, rhombi.)
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 quadrilateral has opposite sides that are not parallel and have angles that are not equal?
All quadrilaterals apart from rectangles. Even parallelograms have adjacent angles that are not equal.
What is the main difference between squares and rectangles?
Squares have four sides of equal length. In rectangles, the opposite sides are equal to one another. In both shapes, the internal angles are all 90°.
Is every rectangle also a square?
Yes all squares meet the requirements of a rectangle. They are equiangular quadrilaterals (have 4 equal angles) and have two pairs of opposite parallel sides. Squares are a subset of all equilateral rectangles. Thus, all squares are rectangles, but only some rectangles are squares.Yes all squares are rectangles because they have four equal angles and two pairs of opposite parallel sides. Not all rectangles are squares however, because only some of them are equilateral.
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.
What is a 3 dimensional shape that has 5 faces 3 are small rectangles and 2 are large rectangles?
There isn't: for all faces to be rectangles there have to be 6, of which opposite sides are equal in length and breadth. (A cuboid)
