Describe the characteristics that make a quadrilateral a trapezoid and what an isosceles trapezoid and a right trapezoid must have?
A quadrilateral that has one (and only one) pair of parallel sides is a trapezoid. It is isosceles of the non-parallel sides are of equal length. It is right angled if any one of the angles is 90 degrees.
What shapes are quadrilaterals but not parallelograms or trapezoids?
Any shape with four straight sides is a quadrilateral. A trapezoid has one pair of parallel sides, and a parallelogram has two pairs of parallel sides. So any shape with four straight sides and no parallel sides is a quadrilateral that is not a parallelogram or trapezoid.
What is true about an isosceles trapezoid?
its non parallel sides are equal. it is vertically symmetrical. any one pair of sides are parallel like in all trapeziums. the co-interior angles between the parallel sides sum up to 90 degrees.
Why is a trapezoid a quadrilateral but not a parallelogram?
Because a quadrilateral is any four-sided shape, whereas a parallelogram must have opposite sides and equal angels. A trapezoid only has two sides and equal angles.In other words, a parallelogram has 2 pairs of parallel sides but a trapezoid only has one pair (top and bottom).
Is a quadrilateral that is not a parallelogram a trapezoid?
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.
Does a trapezoid have no equal sides?
A trapezoid need not have any equal sides, but it may have some equal sides. The only requirements to be a trapezoid, is that it has 4 sides, and at least one pair of parallel sides.
How does a trapezoid differ from other quadrangles?
A trapezoid has only one pair of parallel sides while other quadrilaterals have two pairs of parallel sides. also the trapezoid doesn't have to have any sides that are equal in length.
Which figures have opposite sides equal?
Any regular polygons with an even number of sides can have opposite sides equal and parallel.For quadrilaterals, if any two sides are equal and parallel, the other two sides must also be equal and parallel, and it is a parallelogram (square or rhombus). If the equal sides are not parallel, the figure is a trapezoid (UK trapezium).
What is the difference between trapezoid and a rhombus?
A trapezoid has one pair of parallel sides, a rhombus has two.A trapezoid can have at most three sides of equal length, though it need not have any. All four sides of a rhombus must be the same length.
Describe the characteristics that make a quadrilateral a trapezoid and what an isosceles trapezoid and a right trapezoid must have?
A quadrilateral that has one (and only one) pair of parallel sides is a trapezoid. It is isosceles of the non-parallel sides are of equal length. It is right angled if any one of the angles is 90 degrees.
Does a trapazoid has any parellel sides?
A trapezoid has one pair of parallel sides.
What shapes are quadrilaterals but not parallelograms or trapezoids?
Any shape with four straight sides is a quadrilateral. A trapezoid has one pair of parallel sides, and a parallelogram has two pairs of parallel sides. So any shape with four straight sides and no parallel sides is a quadrilateral that is not a parallelogram or trapezoid.
What is the difference between square and a trapezoid?
A trapezoid is a four-sided figure with two parallel sides. The other two sides are not parallel. A square is a special case of a rectangle, which is a four-sided figure with all four sides having the same length.
What is true about an isosceles trapezoid?
its non parallel sides are equal. it is vertically symmetrical. any one pair of sides are parallel like in all trapeziums. the co-interior angles between the parallel sides sum up to 90 degrees.
Why is a trapezoid a quadrilateral but not a parallelogram?
Because a quadrilateral is any four-sided shape, whereas a parallelogram must have opposite sides and equal angels. A trapezoid only has two sides and equal angles.In other words, a parallelogram has 2 pairs of parallel sides but a trapezoid only has one pair (top and bottom).
Can any side of a trapezoid can be called a base?
The two parallel sides are called the bases, and the two non-parallel sides are the legs. If you call any other pair of sides the bases, the formula for the area of the trapezoid will no longer work.
Is a quadrilateral that is not a parallelogram a trapezoid?
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.
