1.	In the given figure, `angle ABC=90^(@) and BD bot AC`. If `BD=8 cm, AD=4 cm` find CD.
Answer» Correct Answer - `CD=16 cm` In `Delta DBA and Delta DCB`, we have `angle BDA= angle CDB` and `angle DBA= angle DCB [ "each" =90^(@)-angleA]`. `:. Delta DBA~ Delta DCB`. `:. (BD)/(CD)=(AD)/(BD) rArr CD=(BD)/(AD)`
