Properties of a Parallelogram
How to solve this PSLE question ?
I realized that we (girls) could have solved this problem faster and easier if we knew the
properties of a parallelogram.
A 4-sided flat shape with straight sides where opposite sides are parallel.
* opposite sides are equal in length, and
* opposite angles are equal (angles "a" are the same, and angles "b" are the same)
NOTE: Squares, Rectangles and Rhombuses are all Parallelograms!
We finally solved the problem !
