Are all paralelograms rectangle?
No, only those with 90 degree angles
How is the rectangle different from the rhombus?
A rectangle is composed of four ninety degree angles. While the sum of the four angles of the rhombus only have to add up to 360
Do the diagonals of a rectangle bisect the angles?
The diagonals of a rectangle bisect the angles only if the rectangle is a square.
Which description does not guarantee that a quadrilateral is a rectangle?
A quadrilateral is not necessarily a rectangle. The only time this is not true is in the case of a square on a quadrilateral without four 90 degree angles.
Does a rectangle only have 2 right angles?
A rectangle, by definition, has 4 right angles.
Why is a rectangle a parallelogram but a parallelogram is not a rectangle?
A rectangle has three rules: -2 pairs of parallel sides -four 90 degree angles -2 pairs of congruent sides A parallelogram has three rules: -2 pairs of parallel sides - 2 pairs of congruent angles -2 pairs of congruent sides The only difference is that a rectangle has 90 degree angles, which a parallelogram doesn't have. That's why a parallelogram can't be a rectangle. A rectangle follows all the rules of being a parallelogram, so it can be a parallelogram.
What has only right angles?
A rectangle.
Do diagonals cross at right angles on a rectangle?

Why is a rectangle a square?

Is a square always a rectangle and rhombus?
Yes, a square is a specific type of rectangle or rhombus. The only qualifications for a rectangle are that the corners have the make 90 degree angles and the sides have to be parallel, any square meets those qualifications.
What is a four sided shape with two right angles?
If ONLY two right angles, then it could be a right angled trapezium or a kite If more than two it must be a rectangle (a square is an equilateral rectangle).
Do the diagonals of a rectangle always intersect at right angles?
only if the rectangle is square
