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
