Yes, all trapezoids must have one pair of congruent sides.
All trapezoids have four sides, and all of them have one set of parallel lines
Yes.
No, trapezoids are not rectangles. While both shapes have four sides, rectangles have opposite sides that are equal in length and all interior angles are right angles, whereas trapezoids have only one pair of opposite sides that are parallel.
The main difference between squares and trapezoids is that, while the length all four sides of a square are equal, trapezoids have two sides with equal length and two sides of different length. Also, the opposite pairs of sides in a square are parallel, while only one pair of sides in a trapezoid is parallel.
Yes, all trapezoids must have one pair of congruent sides.
All polygons with 4 sides are called quadrilaterals which includes trapezoids
All trapezoids have four sides, and all of them have one set of parallel lines
yes - all the rhombuses. By definition a trapezoid has two parallel sides, a rhombus also has two parallel sides - because both pairs of opposite sides are parallel. So all rhombuses are trapezoids (but not all trapezoids are rhombuses)
Yes.
No. Most Trapezoids are not isosceles. The non parallel sides must be congruent to be isosceles.
No, trapezoids are not rectangles. While both shapes have four sides, rectangles have opposite sides that are equal in length and all interior angles are right angles, whereas trapezoids have only one pair of opposite sides that are parallel.
Only if it's an isosceles trapezoid otherwise all trapezoids have exactly one pair of parallel sides that are of different lengths
Some people define trapezoids as having at least one pair of parallel sides. By this definition, all parallelograms are trapezoids, though not all trapezoids are parallelograms.Some people define trapezoids as having exactly one pair of parallel sides. By this definition, the terms "trapezoid" and "parallelogram" are mutually exclusive.
No but a trapezoid does belongs to the class of 4 sided quadrilaterals.
By definition, a trapezoid only must have exactly one pair of parallel sides. An isosceles trapezoid does have one pair of congruent sides, but not all trapezoids will have exactly one pair of congruent sides.
A polygon is a 2 dimensional shape with three or more sides that is closed in. A trapezoid is a four sided shape with only one pair of parallel sides. Therefore all trapezoids are polygons.
