What are the quadrilaterals whose diagonals cross at right angles?
They are either kites or (if the diagonals bisect each other) rhombuses.
The shape is not rectangle but looks like one?
It would have to be either a Parallelogram or a Trapezoid, both are Quadrilaterals. The rectangle is a type of Parallelogram.
Is a rectangle a trapezoid?
a trpazoid actualy has at least 1 pair of parallel sides, a rectangle has 2 pairs os parallel sides
What is a quadrilateral with opposite sides that are parallel and congruent?
a quadrilateral isa polygon with four sides and four vertices. Sometimes the word quadrangle is used. The interior angles add up to 360 degrees. Quadrilaterals are either simple (not self- intersecting) or complex (self-intersecting). Quadrilaterals and polygons in general, are broadly divided into two groups: convex and concave polygon.
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.
Can All quadrilaterals can be classified as either parallelograms or trapezoids?
No because all quadrilaterals are 4 sided shapes which includes parallelograms, trapezoids, squares, rectangles, kites......etc
Are all quadrilaterals either trapezoids of parallelograms?
I'm going to make this simpler to look at. Quadrilaterals are 4 sided figures with sub-groups which are: squares,rectangles,trapezoids,parallelogrames, and rhombuses. Those are the main ones though I'm sure there more put there in the world.
Are all quadrilaterals either trapezoids or parallelograms?
No. A trapezoid must have one pair of parallel sides, and a parallelogram must have two pair.But a quadrilateral in general doesn't necessarily have any parallel sides.
What quadrilaterals have only one pair of parallel sides?
Trapezoids. All other quadrilaterals either have two pairs of parallel sides or none.
Are parallelograms trapezoids?
There is disagreement among authors on this. It depends on your definition of a trapezoid. A parallelogram is defined as a quadrilateral with opposite sides parallel. A trapezoid is defined as either- a quadrilateral with at least one pair of parallel sides, or- a quadrilateral with exactly one pair of parallel sides.Therefore, if you go with the former definition, yes all parallelograms are trapezoids, because all parallelograms have at least one pair of parallel sides. If you use the latter definition, no.The "at least one" definition is consistent with the trapezoid's uses in higher math, such as the trapezoidal rule for approximating integrals.You can say, however, that all trapezoids are not parallelograms.
Which group of quadrilaterals has diagonals that bisect their opposite angles?
Either a square or rectangle fit this description.
Do parallelograms have equal sides?
Some do, some don't. A parallelogram that has equal sides is usually called either a "rhombus" or a "square". None of the other parallelograms do.
What is the shape of a lateral face of a prism?
The lateral faces of a prism are either squares, rectangles or parallelograms. If the prism is oblique then the faces must be parallelograms and not rectangles or squares.
Do the rectangular parallelogram both have the same area explain why or why not?
No. A rectangle and a parallelograms are desciptions of quadrilateral shapes. There is no indication of the size of either. So some rectangles are smaller than some parallelograms and some parallelograms are smaller than some rectangles.
How do you split a rhombus to make two parallelograms?
Bisect the rhombus with a line parallel to either of the pairs of sides.
Do some trapezoids have 4 congruent sides?
No, if a four-sided figure has equal sides, it is either a rhombus or a square, but not a trapezoid.
How are clouds classified by name?
They are classified as either cumulus, stratus or cirrus clouds.
