The definition of a rectangle is a four-sided figure with four 90-degree angles and lines that are either two different lengths (two lines same length, other two lines same size), or all the lines are the same length (a square). A rhombus has four sides that are the same length with no restriction on its angles.
Harriet Tubman became famous as a âconductorâ on the Underground Railroad during the turbulent 1850s. Born a slave on Marylandâs eastern shore, she endured the harsh existence of a field hand, including brutal beatings. In 1849 she fled slavery, leaving her husband and family behind in order to escape. Despite a bounty on her head, she returned to the South at least 19 times to lead her family and hundreds of other slaves to freedom via the Underground Railroad. Tubman also served as a scout, spy and nurse during the Civil War.
Undeterred, she found other slaves seeking freedom and escorted them to the North. Over the course of 10 years, and at great personal risk, Tubman led hundreds of slaves to freedom along the Underground Railroad, a secret network of safe houses where runaway slaves could stay on their journey north to freedom.
