no, because a octagon is a quadrilaterals and they have 8 angles
the two types of quadrilaterals that have four right angles are a square and a rectangle
Rhombuses and trapezoids have no right angles by definition.
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
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.
A quadrilateral with 0 right angles is a trapezoid, i know it looks like it has right angles IT DOES NOT!
"Quadrilateral" simply means "four sided". Some quadrilaterals do have right angles; squares or rectangles, for example. Some have one or two right angles, but some don't have any right (90 degree) angles.
No, only squares and rectangles have 4 right angles.
A rectangle or a square are sets of quadrilaterals with two pairs of right angles. They each have two pairs of right angles and two sets of equal sides.
a quadrilateral can contain 2 right angles,one obtuse and one acute angle.
no,all quadrilaterals have 4 right angles
Rectangles and squares.
Squares, rectangles etc
rhoumbus & trapazoid
It can.Quadrilateral means "four sides", and squares and rectangles do have right angles. Rhombuses are quadrilaterals, but do not have right angles.
Rectangles have 2 pairs of right angles.
Rectangles have only right angles (which means 90o angles) whereas quadrilaterals can have any kind of angles, as long as they have 4 sides.
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.
Quadrilaterals are polygons having four sides. Quadrilaterals may have 1, 2, or 4 right angles. It is impossible for a quadrilateral to have exactly 3 right angles because the fourth angle would also be a right angle.
A square or a rectangle are both quadrilaterals consisting of four right angles.
