Given:  Rhombus RSTV (not shown) with diagonals


Find:  RS, the length of a side 
To find:
RS, the length of a side.
The basic properties of rhombus:
1) All the properties of a parallelogram apply (the ones that matter here are parallel sides, opposite angles are congruent, and consecutive angles are supplementary).
2) All sides are congruent by definition.
3) The diagonals bisect the angles.
4) The diagonals are perpendicular bisectors of each other.
Calculation:
Given: Rhombus RSTV with diagonals
RT = 8 and SV = 6
Consider the rhombus.
To find RS:
From the property, in rhombus, diagonals are perpendicular bisectors.
