15. Group 1 and 2: Study the figure
on the next slide and name as
many parallelograms as you
can. If the parallelogram is
special, tell whether if it is a
rectangle, rhombus or square.
17. Group 3 -5: Using the Cartesian
plane, plot each sets of points
and connect consecutively to
form a quadrilateral. Identify
whether the figure is a
parallelogram or not.
