# a quadrilateral with two pairs of parallel sides

If only one pair of opposite sides is required to be parallel, the shape is a trapezoid. If the shape (a quadrilateral) has only 2 parallel sides, it is a trapezoid (UK trapezium).A shape with four sides and two sets of parallel sides is a parallelogram (rectangle, square, rhomboid, rhombus) because these figures have four sides and two sets of parallel sides. 1) The two parallel sides of different legths and constitute the bases of a trapezoid. Which quadrilateral has only 2 parallel sides? In fact it is a 4-sided polygon, just like a triangle is a 3-sided polygon, a pentagon is a 5-sided polygon, and so on. Quadrilateral: A quadrilateral is defined as the geometrical figure having four sides and four vertices. The definition of trapezoid is a quadrilateral with at least two parallel sides. B. (This definition excludes rhombi. But all quadrilaterals are polygons. Three examples are shown below. A parallelogram has two parallel pairs of opposite sides. A kite is a quadrilateral with exactly two pairs of adjacent congruent sides. when two sides cross over, we call it a "Complex" or "Self-Intersecting" quadrilateral, like these: They still have 4 sides, but two sides cross over. All quadrilaterals are polygons with four sides - True. parallelogram rhombus rectangle square A quadrilateral with only one pair of parallel sides … All quadrilaterals are polygons with two pairs of parallel sides - False. A regular dodecagon (12 sides) will have six pairs of parallel sides , but a regular tridecagon (13 sides) will have no parallel sides. A quadrilateral is a polygon. (1) Parallelogram A parallelogram is a quadrilateral with two sets of parallel sides. A quadrilateral is a four-sided polygon with four angles like- parallelogram, rectangle, square, trapezoid, rhombus. A trapezoid, in which the non-parallel sides are equal in length, is called isosceles.A quadrilateral with two separate pairs of equal adjacent sides is commonly called a kite. Some textbooks say a kite has at least two pairs of adjacent congruent sides, so a rhombus is a special case of a kite.) Polygon. A quadrilateral with two pairs of parallel sides, opposite sides are congruent, opposite angles are congruent, consecutive angles are supplementary, if it has … A quadrilateral with two sets of parallel sides and four right angles is a _____. The regular polygon will have half as many pairs of parallel sides as it has sides (because two sides make a pair). A scalene quadrilateral is a four-sided polygon that has no congruent sides. 2) The two equal anglesare the base angles of the trapezoid, and mean that it is an isosceles trapezoid. An isosceles trapezoid is truncated isosceles triangle. Oh Yes! C. The opposite or facing sides of a parallelogram are of equal length, and the opposite angles of a parallelogram are equal. A. (2) SquareA square is a regular quadrilateral. Not all polygons are quadrilaterals. Complex Quadrilaterals. That is an interesting property of regular polygons, and of parallel sides. Special Quadrilaterals. In word problems, be careful not to assume that a quadrilateral has parallel sides or equal sides unless that is stated.
