The Great Bridge over the Charles River connected Cambridge, Massachusetts to Little Cambridge, which was the name for Allston-Brighton before it separated from Cambridge in 1807, first becoming the town of Brighton and finally joining the city of Boston in 1874. The Great Bridge was built in 1660-1662 at what was then called Brighton Street, and was the first bridge to span the Charles. A toll was authorized in 1670, rebuilt in 1862.

The transept is the area set crosswise to the nave in a cruciform ("cross-shaped") building in Romanesque and Gothic Christian church architecture. The transept separates the nave from the sanctuary, whether apse, choir, chevet, presbytery or chancel.

Right triangle ABC with angles A, B, C to be used for finding distance across a river. This is a trigonometry problem. Wishing to determine the width of the river, I observed a tree standing directly across on the bank. The angle of elevation of the top of the tree was 32 degrees. At 150 ft. back from this point and in the same direction from the tree the angle of elevation of the top of the tree was 21 degrees. Find the width of the river.
