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.
nope it is possible for a trapeziod to have three congruent sides
Yes, all trapezoids must have one pair of congruent sides.
Only if it's an isosceles trapezoid otherwise all trapezoids have exactly one pair of parallel sides that are of different lengths
No. Most trapezoids don't even have one pair of congruent sides. Only isosceles trapeoids have one pair; none have more than one pair.
No, a parallellogram is a quadrilateral with two pair of congruent sides and a trapezoid is a quadrilateral with only one pair of congruent sides.
they have to because if they didn't it would be some sort of pentagon. so... yes
This quadrilateral is a trapezoid. In a trapezoid, one pair of opposite sides is parallel, and one pair of opposite sides is congruent. The other two sides are not parallel or congruent.
Trapezoids have only one pair of parallel sides.
Yup :p
"It is a quadrilateral with exactly one pair of parallel sides." is the true one. Some people define it as having at least one pair of parallel sides, so if your teacher is one of those people then all of the answers are wrong, but since all of the other answers are definitely wrong then this is the only one that could be right.
By definition, all trapezoids must have one pair of parallel sides. Therefore, an isosceles has one pair of congruent angles.
