Bibi is using a software program that allows her to change the shape of a two-dimensional figure by making changes to the sides. She starts with a quadrilateral with opposite sides parallel. She stretches the shorter edges of the quadrilateral to make all four sides congruent.

Which statement best describes the figure that she created?
Answer

She changed a kite to a square.

She changed a rectangle to a square.

She changed a trapezoid to a rhombus.

She changed a parallelogram to a rhombus.

phi · Answer

A parallelogram is a quadrilateral with two pairs of parallel sides

anonymous · Answer

i though it was the second answer because a rhombus only has congruent sides if their opposite

phi · Answer

rhombus has equal sides (congruent sides) But its angles are not all equal. According to wikipedia http://en.wikipedia.org/wiki/Trapezoid#Definition There is disagreement on the definition of trapezoid. So the answer depends on whether a trapezoid is defined as one pair or two pair of parallel lines. Personally, I think of trapezoids as having only one pair...

The best answer is the last.
