USA. Benjamin Banneker (1731-1806) is one of the great American heroes of
all time. The son and grandson of Africans captured and enslaved, he was
fortunate to have been born free. He inherited the family farm where he worked
hard all of his life. As a child he had a few months of schooling. Everything else
he had to do on his own. He loved mathematics and science but did not get a
chance to learn astronomy until he was in his fifties. Then he performed a near
miracle, learning it all in less than a year. In his hand-written journal, he
recorded two right triangle examples that interested him. You can solve them
here and remember the great man who enjoyed geometry.
On the page in his journal next to the August 1775 astronomy
calculations, Banneker wrote, in the style of that time: Suppose a ladder 60
feet long be placed in a Street so as to reach a window on the one Side 37
feet high, and without moving it at bottom, will reach another window on
the other side of teh Street which is 23 feet high, requiring the breadth of
the Street.
