list 10 figures around you and identify the acute,obtuse and right angles found in them.
A bio sketch is a brief summary of you or someone Else's professional /educational accomplishments, publications, and affiliations--an abbreviated curriculum vitae--meant to highlight important aspects of your training, experience, and areas of interest.
In plain words...it's a "light sketch" of a persons life.
I was taught that a biography is about someone else while an autobiography is about one's self. So an autobiographical sketch would be a bio sketch of your own life while a biographical sketch is a bio sketch of anybody Else's life.
