We will be happy to post videos as per your requirements also. Do write to us.In this section we will discuss rhombus and its theorems.
|1) ABCD is a rhombus.||1) Given|
|2) AB = BC = CD = DA||2) Properties of rhombus.|
|3) OB = OD and OA = OC||3) As Parallelogram is a rhombus so diagonal bisect each other.|
|4) BO = OD||4) From (3)|
|5) BC = DC||5) Properties of rhombus.|
|6) OC = OC||6) Reflexive (common side)|
|7) ΔBOC ≅ ΔDOC||7) SSS Postulate.|
|8) ∠BOC = ≅ ∠DOC||8) CPCTC|
|9)∠BOC + ∠DOC = 180||9) Linear pair angles are supplementary.|
|10) 2∠BOC = 180||10) Addition property|
|11) ∠BOC = 90||11) Division property|
|12) ∠BOC = ∠DOC = 90||12) As these two angles are congruent.|
