Make sure you know the properties of each of the following special quadrilaterals, you need to be able to recognize and draw each of these. Later you will need to be able to use these properties to solve math problems.
A parallelogram:
has point symmetrie
has opposites of the same length
has diagnonals that cut each other in half
has opposite angles that are equal
A rhombus:
has diagonals that for the axes of symmetry
has diagonals that intecest at an angle of 90o (perpendicular)
has diagonals that are bisectors of the angles
A rhombus is a special parallelogram, so the same properaties apply:
has point symmetrie
has opposites of the same length
has diagnonals that cut each other in half
has opposite angles that are equal
A trapezium:
has at least one pair opposite sites that are parallel.
A special trampezium called a isosceles trapezium:
also has two not parallel sides that are the same size.
This isosceles trapezium has one axis of symmetry
A kite:
has two pairs of equal adjacent sides
one pair of equal opposite angles
has diagonals that intersect at an 90o degree angle (perpendicular)
has at least one diangonal that is an axis of symmetry
