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.
Do all parallelograms have at least one right angle?
The simple answer is no, not all parallelograms have at least one right angle. However, there are some that do. Rectangles and squares are 'special' parallelograms that all have at least one right angle.
Why is the angle sum of a trapezoid 360?
Because the angle sum of all quadrilaterals is 360 degrees.
Do all quadrilaterals have at least one line of symmetry?
Not all 4 sided quadrilaterals have lines of symmetry.
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 a least 1 right angle?
No.
Do all quadrilaterals at least one right angle?
No
Do all quadrilaterals have a least one right angle?
Some do, some don't.
Do all quadrilaterals have at lease 1 right angle true or false?
no,all quadrilaterals have 4 right angles
Do all irregular quadrilaterals have no right angels?
A kite can have on right angle, even two!
Do all quadrilaterals have at least 1 right angles?
No.

Do all quadrilaterals have at least one right angels?
no,what about a trapizoid or rhombus
Do all quadrilaterals have at least one right angle true or false?
False because it depends on what type of a 4 sided quadrilateral it as for example a square has 4 right angles whereas rhombus has no corner right angles.
Do all parallelograms have at least one right angle?
The simple answer is no, not all parallelograms have at least one right angle. However, there are some that do. Rectangles and squares are 'special' parallelograms that all have at least one right angle.
Do all triangles have at least 1 right angle?
only right tringles or HL triangles have at least 1 right angle
What polygon has 1 right angle and only 1 set of parallel lines?
There are lots of polygons like that. If by 1 right angle, you mean exactly 1 right angle, there are no such quadrilaterals, but there are pentagons (in fact n-gons for all n>=5.)
