This is a learning material (Module). It contains the properties of the diagonals of special quadrilaterals, conditions of a parallelogram. It helps develop student's understanding on the properties of the diagonals of special quadrilaterals and the conditions sufficient to guarantee that a quadrilateral is a parallelogram.
Objective
1. to apply inductive/deductive skills to derive the properties of the diagonals of special
quadrilaterals
• rectangle
• square
• rhombus
2. to verify sets of sufficient conditions which guarantee that a quadrilateral is a
parallelogram
3. to apply the conditions to prove that a quadrilateral is a parallelogram
4. to solve routine and non-routine problems
