来源：该词源于希腊语"trapezion"，意为"小桌子"，因为梯形的形状类似于一个小桌子。
例句：
"The area of a trapezoid is equal to the sum of its bases, multiplied by its height, divided by 2."
"梯形的面积等于两个底边之和乘以高除以二。"
"The trapezoid has a longer base and a shorter base."
"这个梯形有一个长底边和一个短底边。"
"The trapezoid was used to find the area of the irregular shape on the ground."
"梯形被用来求地面上不规则形状的面积。"
