PROBLEM:
Parallelogram or not?
[tex] \huge \boxed{ \large{\tt (0,0); (-4,0); (-3,2); (-1,2)}}[/tex]
ANSWER:
• The given points forms a trapezoid. A trapezoid has one pair of parallel sides and might have a pair of sides that is congruent in measure, an isosceles trapezoid.
• On the other hand, a parallelogram has two pairs of parallel sides. Thus, a parallelogram is also a trapezoid yet, does not guarantee that a trapezoid is a parallelogram.
• Trapezoid and parallelograms as well as kite are all quadrilaterals. Example of parallelograms are square, rectangle and rhombus.
