I apologize in advance for my English, but I really want to learn.
I took two lines and intersected them. |BD| and |AC| parallel but no length information
Question: Is it possible to find the length of |EF|? and how? they seem to be related but at the same time the information is missing
[BD] // [AG] Parallel
|BD| & |AG| : No length information
|BG| & |AG| & |DH| & |CH| : have length information
Question: |BG| & |AG| & |DH| & |CH| ------> |EF| related? is there an equation?
i know: |BD| and |GC| information, gives us an equation by similarity.
