The other two sides are called the legs (or the lateral sides) if they are not parallel; otherwise, the trapezoid is a parallelogram, and there are two pairs of bases. A scalene trapezoid is a trapezoid with no sides of equal measure, [3] in contrast with the special cases below.
The area of an isosceles (or any) trapezoid is equal to the average of the lengths of the base and top (the parallel sides) times the height. In the adjacent diagram, if we write AD = a, and BC = b, and the height h is the length of a line segment between AD and BC that is perpendicular to them, then the area K is
Although often referred to as the area of a circle in informal contexts, strictly speaking, the term disk refers to the interior region of the circle, while circle is reserved for the boundary only, which is a curve and covers no area itself. Therefore, the area of a disk is the more precise phrase for the area enclosed by a circle.
The formula for the area of a circle (more properly called the area enclosed by a circle or the area of a disk) is based on a similar method. Given a circle of radius r, it is possible to partition the circle into sectors, as shown in the figure to the right. Each sector is approximately triangular in shape, and the sectors can be rearranged to ...
Irregular quadrilateral (British English) or trapezium (North American English): no sides are parallel. (In British English, this was once called a trapezoid. For more, see Trapezoid § Trapezium vs Trapezoid.) Trapezium (UK) or trapezoid (US): at least one pair of opposite sides are parallel. Trapezia (UK) and trapezoids (US) include ...
Patriots No. 3 overall pick Drake Maye continues to improve each week, and as a result, fantasy managers have been able to trust Henry to produce. Henry is New England's leading receiver and has ...
The polygon's unsigned area (the total area it surrounds) is the sum, rather than the difference, of these areas. For an antiparallelogram with two parallel diagonals of lengths p {\displaystyle p} and q {\displaystyle q} , separated by height h {\displaystyle h} , this sum is h p q / ( p + q ) {\displaystyle hpq/(p+q)} .

One by one his platoon buddies were getting out of the Marines. Finally Joseph left too, and came home to Connecticut on Jan. 12, 2011. He left behind Frankie, his beloved pit bull mix; there was no place for him in Debbie’s two-floor duplex. A day or two later, Joseph called the VA to get help with his PTSD. He was told to send an email request.
