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.
