- A trapezoid is a quadrilateral with one pair of parallel lines. Example 1 of legs and the Bases Example 2 of legs and the Bases. Bases-The two parallel lines are called the bases. The Legs-The two non parallel lines are the legs.

- A trapezoid is a quadrilateral with only one set of parallel sides. They absolutely cannot have two sets of parallel sides. So when trapezoids start their own party after being kicked out of the quadrilateral party, we can be certain that rectangles, squares, and parallelograms will definitely not be on the guest list.

Is a concave trapezoid possible? No, you can't have 2 sides parallel and still make the shape concave. A concave quadrilateral, on the other hand, looks somewhat like an arrowhead. Source(s): http://upload.wikimedia.org/wikipedia/co... No...trapezoid is a quadrilateral with one pair of parallel sides. It is the opposite, which is called convex.

- No. In order for a quadrilateral to be a trapezoid, it must have exactly one pair of parallel sides. A right trapezoid, therefore, has exactly one pair of right angles. However a square would be a right parallelogram (which is the current definition of a rectangle). In the UK, the word trapezoid refers to a quadrilateral with no sides parallel. They use the word trapezium to refer to what Canadians call a trapezoid. To make matters worse, North Americans call a quadrilateral with no parallel sides a trapezium. Here's a summary.

Art Definitions, Glossary of Terms The trapezoid has one pair of parallel sides. The parallelogram, rectangle, and square all have two pairs of parallel sides. Other less common shapes with parallel sides include any of the '-gons' with an even number of sides, such as a hexagon, octagon, decagon, etc. A hexagon and octagon with parallel sides.

What is a Trapezoid? (Part 1) There are two competing definitions for trapezoid: The exclusive definition of a trapezoid states that a trapezoid has exactly one pair of opposite sides parallel. The inclusive definition states that a trapezoid has at least one pair of opposite sides parallel.

Trapezoid (Jump to Area of a Trapezoid or Perimeter of a Trapezoid) A trapezoid is a 4-sided flat shape with straight sides that has a pair of opposite sides parallel (marked with arrows below): A trapezoid: is an Isosceles trapezoid when both angles coming from a parallel side are equal, and the sides that aren't parallel are equal in length.

Trapezoid The parallel sides are called the bases of the trapezoid and the other two sides are called the legs or the lateral sides (if they are not parallel; otherwise there are two pairs of bases). A scalene trapezoid is a trapezoid with no sides of equal measure, in contrast to the special cases below.n obtuse trapezoid with two pairs of parallel sides is a parallelogram. A parallelogram has central 2-fold rotational symmetry (or point reflection symmetry). There is some disagreement whether parallelograms, which have two pairs of parallel sides, should be regarded as trapezoids.

Is a trapezoid a parallelogram? Why or why not? A trapezoid is a quadrilateral with two opposite sides parallel. A parallelogram fulfils that requirement but also has the other two sides parallel. So a trapezoid can be a parallelogram or, to put it the other way, a parallelogram is a special case of a trapezoid. This (from Wikipedia) is the definitive diagram.

True or False ''Some rectangles are trapezoids''? A trapezoid is defined as a four-sided polygon with one pair of parallel sides. A rectangle is a four-sided polygon with each side parallel to its opposite side (basically, two pairs of parallel sides) and four right angles, so all rectangles could technically be considered as trapezoids. Hope this helps.

Parallelogram and trapezoid Signs of a parallelogram. Rectangle. Rhombus. Square. Trapezoid. Isosceles trapezoid. Midline of a trapezoid and a triangle. Parallelogram ( ABCD, Fig.32 ) is a quadrangle, opposite sides of which are two-by-two parallel. Any two opposite sides of a parallelogram are called bases, a distance between them is called a height ( BE, Fig.32 ). Properties of a parallelogram.

Parallelogram and trapezoid and parallel to them: EF || AD and EF || BC. A trapezoid with equal lateral sides ( AB = CD ) is called an isosceles trapezoid. In an isosceles trapezoid angles by each base, are equal ( A = D, B = C ). A parallelogram can be considered as a particular case of trapezoid. Midline of a triangle is a segment, joining midpoints of lateral sides of a triangle.

- A trapezoid has two bases, each of which is one of the parallel sides. The other two sides that aren't parallel to each other are called the trapezoid's legs. Since only the bases are parallel and the legs are not, we can think of this scenario as two nonparallel transversals cutting across a pair of parallel lines.

- First and fore most a Trapezoid is a quadrilateral which is a 4 sided plane shape. It has 4 lines. It is a closed shape. Two of the lines are parallel. It is a simple quadrilateral - meaning the sum of it's angles is 360 degrees.

- Definition: A trapezoid has at least 1 pair of parallel sides. • A trapezoid has no axes of reflectional symmetry. • A trapezoid has no rotational symmetry (Order 1). Note: Having no rotational symmetry means that the figure must be rotated a full 360º to again appear in it original position.

Trapezoid In the trapezoid below, the midpoints of the non-parallel sides are points S and V. The midsegment is the red line segment from S to V. The midsegment below can be found by. calculating the lengths of the bases 35-16 = 9 (length of upper base) 45-0 =45 (length of lower base) calculating the sum of the bases 9+45 = 54.
