Dagan, Golumbic, and Pinter defined the class of graphs that generalize interval and permutation graphs and correspond to this shape. Romberg's algorithm recursively uses a technique named for this shape that is the two points Newton-Cotes formula. That technique uses small line segments to approximate the definite integral. It's not a triangle, but the isosceles version of this shape has diagonals equal to the square root of the sum of the square of the leg length and the product of the bases. The area of this figure is equal to its height times the length of the central median, which is the average of the bases. For 10 points, name this quadrilateral with a pair of parallel sides.
