An Angle is the difference in the direction of two lines that meet. 256. A Square is a figure that has four equal sides, and four equal angles. A square inch is a square whose side is one inch. A square foot, a square whose side is one foot. The angles of a square are called right angles. 257. A Rectangle is a figure that has four straight sides and four equal angles. The angles of a rectangle are all right angles, 258. The Area or extent of any surface is the number of square units it contains. Thus, if a rectangle is 4 inches long and 3 inches wide the area will be 12 square inches. For it may be divided into 4 rows, each containing 3 square inches or units, and the entire area will be 12 square inches. The method of computing the area of figures that are not rectangular is given in MENSURATION. 259. The area of a rectangle is equal to the product of the numbers that express its length and breadth. The length and breadth must be expressed in units of the same denomination. 1.
