1.  The radius of a circle inscribed in a rhombus if you know diagonals and side  

radius circle inscribed rhombus d

 

DD blue , d blue   -  diagonals of a rhombus

a black  - side  of a rhombus  

O black  - circumcenter    

 

Calculate the radius of a inscribed circle of a rhombus if given diagonals and side ( r  ) :

radius circle inscribed rhombus d F

 

 

2.  The radius of a circle inscribed in a rhombus if you know height  

radius circle inscribed rhombus h

 

h   -  height of a rhombus

a black  - side  of a rhombus  

O black  - circumcenter    

 

Formula for calculating radius of a inscribed circle of a rhombus if given height ( r  ) :

radius circle inscribed rhombus h F
