Best Answer

No. Think of any other four-sided shape which isn't a square or rectangle. Get a piece of paper and draw a random four-sided shape which isn't a square or rectangle (you don't have to be able to name it).

Hint: There are infinitely many.
No only a square and a rectangle 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.

Are all quadrilaterals also squares?

No. A quadrilateral is any four-sided figure. The sides do not have to be of equal length, and the angles do not have to be right angles. So, all squares are quadrilaterals because they have four sides), but not all quadrilaterals are squares.

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.

Does a Quadrilaterals have four angles?

Yes, all Quadrilaterals have four sides, therefore they must have 4 angles.

What is a quadrilateral with 4 angles?

Which quadrilateral always have a 90-degree angles?

The only quadrilaterals that always have all four right angles are the square and the rectangle. All four angles in a quadrilateral must add up to 360 degrees.It is possible to have non-regular quadrilaterals with one or two right angles. A quadrilateral with three right angles becomes either a square or a rectangle, because its fourth angle must also be a right angle.

Do all quadrilaterals have at lease 1 right angle true or false?

How many sides and angles does a quadrilateral have?

All quadrilaterals have four sides and four angles, as well as four vertices.

Do all quadrilaterals have at least 1 right angles?


Every quadlitaeral a rectangle?

No. A quadrilateral is a any closed polygon with four sides. A rectangle is a quadrilateral with four right angles and congruent opposing sides. Therefore, all rectangles are quadrilaterals, but not all quadrilaterals are rectangles.

What is every rectangle?

Every rectangle has four (straight) sides, and four (right) angles. All rectangles are also polygons, quadrilaterals, and parallelograms.

Are all quadrilaterals cyclic quadrilaterals?

No, one example is a kite that DOES NOT have two right angles. It is not a cyclic quadrilateral. A kite that does have two right angles is one.
