RHOMBUS
The properties of rhombus are : All sides are equal Opposite sides are parallel Opposite angles are equal Diagonal bisect each other at
900
Both diagonals are the angles bisector
Both diagonals are line of symetry
Area : Perimeter : 4 x side
Note :d1 = the first diagonal’s length
d2 = the second diagonal’s length

RECTANGLE
The properties of rectangle are : Opposite sides are equal Opposite sides are perallel All angles are equal ( 900 ) Diagonals are equal and bisect each other It has 2 line of symetry and 2 rotational
symetry
Area : l x wPerimeter : 2 ( l + w )
Note :
l = lengthw = width
