The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , is used to find the length of any side of a right triangle.

A square has two diagonals of equal length, which intersect at the center of the square. The ratio of a diagonal to a side is. A regular pentagon has five diagonals all of the same length.

To find the total number of diagonals in a polygon, multiply the number of diagonals per vertex (n – 3) by the number of vertices, n, and divide by 2 (otherwise each diagonal is counted twice).

A square has two diagonals, they are equal in length and intersect in the middle.

The area of a square can be found by multiplying the base times itself. This is similar to the area of a rectangle but the base is the same length as the height. If a square has a base of length 6 inches its area is 6*6=36 square inches.

Listed dimensions are always inside dimensions. The first dimension to measure is length. Length is always the longest side of the box that has a flap. The next dimension is width.

Boxes: Length x Width x Height (See below) Bags: Width x Length (The width is always the dimension of the bag opening.) Labels: Length x Width.
