Best Answer

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.

The quadrilaterals with all angles congruent are rectangles and squares. They are the only quadrilaterals in which all four angles are right angles.

No. There are quadrilaterals that have no right angles.no,what about a trapizoid or rhombus

All apart from square, rhombus, kite and arrowhead.

ALL quadrilaterals have 4 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.

No, only squares and rectangles have 4 right angles.

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.

false

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.
