no..for instance a parallelogram
nun
No. There are quadrilaterals that have no right angles.no,what about a trapizoid or rhombus
no,all quadrilaterals have 4 right angles
No
No.
False. Not all quadrilaterals have at least one right angle. While some quadrilaterals, like rectangles and squares, do have right angles, others, such as trapezoids, parallelograms, and rhombuses, may not have any right angles at all. Quadrilaterals can take on various shapes and angles, so the presence of a right angle is not a requirement.
A kite can have on right angle, even two!
yes
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.
Not always because its possible to have a trapezoid with 2 right angles and an obtuse angle plus an acute angle and the 4 interior angles must add up to 360 degrees
Square and rectangle.
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.
