What has four right angles?
A rectangle. A square is a form of rectangle. (All squares are rectangles, but not all rectangles are squares.) ___________ |__________|
What quadrilateral has all angles congruent?
The quadrilaterals with all angles congruent are rectangles and squares. They are the only quadrilaterals in which all four angles are right angles.
Does all Quadrilaterals have at least one right angles?
No, a quadrilateral does not necessarily have any right angles. If it has a right angle, it will necessarily have four right angles, and will be a rectangle. But not all quadrilaterals are rectangles. As long as a polygon has four sides, it is a quadrilateral. It might have, for example, two angles of 100o and two angles of 80o.
All parallelograms with four right angles are?
Rectangles, because a square can be a rectangle, but a rectangle can't be a square.
What does a rhombus and a rectangles always have in common?
all angles are right angles
What is every rectangle?
Every rectangle has four (straight) sides, and four (right) angles. All rectangles are also polygons, quadrilaterals, and parallelograms.
Why aren't all trapezoids rectangles?
Because they don't have right angles.
Are all parallelograms rectangles?
No. All parallelograms are not rectangles. However, all rectangles are parallelograms. A parallelogram is a four sided figure with its opposite sides parallel to each other. A rectangle is a parallelogram whose four angles are all 90'. A square is a type of rectangle that has all four sides the same length.
Is rectangle a parallellogram?
Yes. A rectangle is a parallelogram that has right angles instead of acute and oblique angles at the corners. But not all parallelograms are rectangles.
Can a parllelagram have 4 right angles?
A parallelogram can have 4 right angles, but instead of being classefied as a parallelogram, it will be more specifically classified as a rectangle, but all rectangles are parallelograms.
What is the maximum number or right angles possible in a quadrilateral shape which is not a square?
All quadrilateral have four angles. It is possible that all four angles are right angles, even if the quadrilateral is not a square (this would be a rectangle).
What is a regular quadrilateral and what is another name for this shape?
A regular quadrilateral is a square. It is a four-sided figure with all sides being the same length and all angles equal (right angles).
Can a rhombus be a parallelogram?
All rhombuses are paralleleograms. Rhombuses are parallelograms in which all four sides are the same length (and the opposite angles are congruent). Squares are rhombuses in which all four angles are right.
What is a quadrilateral with side lengths that are all congruent and four right angles?
Square
What has four sides no right angles but all opposite sites are parallel?
parallelogram
Parallelogram with four right angles?
Rectangle, possibly a square. Definition of rectangle is "parallelogram with one right angle". Think about that and you'll realise that all angles thus have to be right.
What shape has 4 right angle and 4 sides that are all the same length?
A square has four right angles and four sides of equal length.
