Puolisuunnikas

Puolisuunnikas is a Finnish term that translates to trapezoid in English. A puolisuunnikas is a quadrilateral with at least one pair of parallel sides. The parallel sides are called bases, and the non-parallel sides are called legs. There are different types of puolisuunnikas. A right puolisuunnikas has at least two right angles. An isosceles puolisuunnikas has legs of equal length. The area of a puolisuunnikas is calculated by taking half the sum of the lengths of the bases multiplied by the height. The height is the perpendicular distance between the bases. In Finnish geometry, puolisuunnikas is a fundamental shape studied in elementary and secondary education. Understanding its properties is crucial for solving various geometric problems.
