That is, the height h and the base b are perpendicular to each other; the angle between them is 90°. triangle h l b FIGURE 2 In the square, s is the length of the side, and each side has the same length. In the rectangle, l stands for the length, and w stands for the width. The width is usually the lesser of the two. The b and h in the triangle are the base and height, respectively. The height is always perpendicular to the base. That is, the height and base form a 90°, or right, angle where they meet.
