The three-dimensional figure sides are its flat surfaces. It is parallel to the bases. In the case that the two bases have different lengths (a ≠ b), the height of a trapezoid h can be determined by the length of its four sides using the formula[11]. {\displaystyle s={\tfrac {1}{2}}(a+b+c+d)} {\displaystyle \triangle } [11], Let the trapezoid have vertices A, B, C, and D in sequence and have parallel sides AB and DC. Four-sided polygons are usually referred to as quadrilaterals, quadrangles or sometimes tetragons. As a consequence the two legs are also of equal length and it has reflection symmetry. d In geometry, there are different shapes and sizes such as sphere, cube, cuboid, cone, cylinder, etc. The cotangents of two adjacent angles sum to 0, as do the cotangents of the other two adjacent angles. Then FG is the harmonic mean of AB and DC:[16], The line that goes through both the intersection point of the extended nonparallel sides and the intersection point of the diagonals, bisects each base. Multiplication and addition are associative operations. Multiplication. In Euclidean geometry, a convex quadrilateral with at least one pair of parallel sides is referred to as a trapezium (/trəˈpiːziəm/) in English outside North America, but as a trapezoid[1][2] (/ˈtræpəzɔɪd/) in American and Canadian English. 0 0.

The term trapezium has been in use in English since 1570, from Late Latin trapezium, from Greek τραπέζιον (trapézion), literally "a little table", a diminutive of τράπεζα (trápeza), "a table", itself from τετράς (tetrás), "four" + πέζα (péza), "a foot; end, border, edge". Surface area and volume are calculated for any three-dimensional geometrical shape. [4], The first recorded use of the Greek word translated trapezoid (τραπεζοειδή, trapezoeidé, "table-like") was by Marinus Proclus[dubious – discuss] (412 to 485 AD) in his Commentary on the first book of Euclid's Elements.[5]. or a truncated pyramid if you mean a pyramid with a square base.
