How many congruent angles does an isosceles trapezoid have?
By definition, all trapezoids must have one pair of parallel sides. Therefore, an isosceles has one pair of congruent angles.
Is a tapezoid a rectangle?
No; A trapezoid must have two pairs of parallel sides, while a trapezoid only requires one pair of parallel sides.
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.
Why can a square never be a trapezoid?
Sure it can. A trapezoid has two parallel sides; a square has both pairs of side parallel. Therefore, all square are automatically trapezoids.
What are the rules of a trapezoid?
A trapezium must have one pair of parallel sides and the other sides must not be parallel - since in that case it becomes a parallelogram.
Do all trapezoids have exactly one pair of congruent sides?
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.
Why is an isosceles trapezoid irregular?
Because it does't have 4 equal sides and 4 equal angles as for example such as a square.
How many congruent angles does an isosceles trapezoid have?
By definition, all trapezoids must have one pair of parallel sides. Therefore, an isosceles has one pair of congruent angles.
Does a trapezoid have three congruent sides?
An isosceles trapezium will have two and can have three congruent sides. But the base and top MUST be different.
Is a tapezoid a rectangle?
No; A trapezoid must have two pairs of parallel sides, while a trapezoid only requires one pair of parallel sides.
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.
When are three sides of a trapezoid congruent?
An isosceles trapezium in which the sloped sides are congruent to either the base or the top will have a total of three congruent sides. The top and bottom MUST be different.
Does a trapezoid have 1 set of parallel lines?
A quadrilateral must have one and only one set of a parallel sides to be a trapezoid.
What attribute makes a parrallelogram a special trapezoid?
A trapezoid is a quadrilateral which must have one pair of parallel sides. If the other pair of sides is also parallel then it is a parallelogram.
Why can a square never be a trapezoid?
Sure it can. A trapezoid has two parallel sides; a square has both pairs of side parallel. Therefore, all square are automatically trapezoids.
What are the rules of a trapezoid?
A trapezium must have one pair of parallel sides and the other sides must not be parallel - since in that case it becomes a parallelogram.
How many pairs of parallel sides does a trapezoid has?
One pair. And the other pair must be non-parallel.
