INTRODUCTION
A Quadrilateral is a four-sided polygon with four
angles. There are many kinds of quadrilaterals.
                                        
E.g. The shape ABCD shown here is a
quadrilateral. A
line segment drawn from one.  AC is a diagonal of
quadrilateral ABCD, as is BD.
vertex of a quadrilateral to the opposite vertex
is called a diagonal of the quadrilateral

PROPERTIES OF PARELLOGRAM

• Opposite sides of a parallelogram are parallel
  and equal in length.
• Opposite angles are equal in size.
•                                            
•

Eg
The symbol // represents is parallel to. AB is
parallel to CD is written as AB//CD. Sides AB
and CD are marked with identical arrows to show
that AB //CD. Sides AC and BD are marked with
identical arrows to show that AC //BD.

RECTANGLE
9
PROPERTIES OF RECTANGLES
Opposite sides of a rectangle are
parallel and equal in
length. All angles are equal to 90.

TRAPEZIUM
12
PROPERTIES OF TRAPEZIUM

• A trapezium has one pair of opposite sides
  parallel.
• A regular trapezium has non-parallel sides equal
  and its base angles are equal

Students will be able to find relationship
among angles,sides,and diagonals of
parallelograms.        Students will be able
to find characteristics of quadrilaterals that
indicate that they are parallelograms.       
Students will know how to solve solve practical
problems using the properties of parallelograms
algebraic and coordinate problems using the
properties of parallelograms.        Students
will know how to.
