This geometric figure's namesake numbers are positive integers that can be expressed as the sum of two or more consecutive integers, also called polite numbers.

This shape names a technique less useful than Gaussian quadrature for non-periodic functions, which approximates a curve as many line segments. That "rule", which is generally more accurate than Riemann sums, approximates definite integrals. Although not triangles, they can be right or isosceles, and the area of this polygon is its height times the average of its bases. For 10 points, name this quadrilateral with one pair of parallel sides.
