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
All rectangles have four right what?
Rectangles have four sides and four angles.
Can a rectangle be a square explain?
a rectangle has 4 right angles. A rhombus has four congruent sides. A square has four right angles and four congruent sides. All squares are rectangles because all rectangles have 4 right angles, and all squares have four right angles. But not all rectangles are squares because not all rectangles have congruent sides.
Do some rectangles have no right angle?
No, all four angles with in a rectangle are right angles.
Which quadrilateral has four right angles?
A quadrilateral with four right angles is a rectangle. If all its sides are the same then it is a square.
What has four right angles?
A rectangle. A square is a form of rectangle. (All squares are rectangles, but not all rectangles are squares.) ___________ |__________|
Are paralelagrams ever rectangles?
If the all four angles in a parallelogram are right angles, then it becomes a rectangle.
Do all rectangle's have right angles?
All rectangles have 4 interior right angles.
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.
What is the characteristics of rectangles?
-- It has four sides. -- Opposite sides are parallel. -- All interior angles are right angles.
What is the difference between squares rhombuses and rectangles?
Squares have four sides of equal length and four right angles.Rhombuses (rhombi) have four sides of equal length but the angles are not right angles. Rectangles have four right angles but the sides are not all of the same length.
Are all parallelograms a rectangle?
No, because to have a rectangle, you need to have four right angles, and parallelograms dont have to have right angles. However, all rectangles are parallelograms.
Can a parallelogram be a rectangle rhombus and square?
No, because a rectangle has four sides, and four right angles. So does a square. But, a rhombus has four sides, two obtuse angles, and two acute angles. Even though a rhombus does qualify as a parallelogram, (four sides, four angles) is does not qualify as a rectangle or square because is doesn't have four right angles. All squares are rectangles, but not all rectangles are squares because a rectangle has four sides, and four right angles, but with a square, all the sides have to be the same length.
