no because if 3 sides are the same length, so would the 4th, then you would have a square
Triangles have three sides while trapezoids are quadrilaterals with four sides. Trapezoids have one set of parallel lines. Triangles do not have any sets of parallel lines.
yes, but only in isosceles trapezoides, the sides that are not parallel are the congruen sides.
trapezoids have 4 sides, rhombuses have 4 sides
Trapezoids do not have perpendicular 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)
No but a trapezoid does belongs to the class of 4 sided quadrilaterals.
Only when they are isosceles trapezoids.
no
Yes! 4 sides :)
We don't know who said that, but it's not true. Some quadrilaterals are trapezoidsand some aren't.A quadrilateral is any drawing with four sides.A trapezoid is any drawing with four sides and two of the sides are parallel.So all trapezoids are quadrilaterals. But there are a lot of other quadrilateralsthat aren't trapezoids.
Yes, because trapezoids have one pair of parallel sides.
Trapezoids are not parallelograms. Trapezoids are 4 sides with 1 set of parallel sides. Parallelograms are 4 sided with opposite sides that are parallel.
