That all the degrees equal 360 and I think that it has at least one set of parallel lines.
Yes of course! :)
never
no. trapezoids are never parallel
Yes. Quadrilaterals means a closed shape with four sides, and a trapezoid has four sides, and is a closed shape.
1/2(h)(b1+b2)
hexagons, triangles, rectangles, trapizoids, and many other shapes. circles do not tessallate
No. Parallelograms are never trapezoids because in order to be a parallelogram there has to be two sets of parallel sides. A trapezoid only has one set of parallel sides.
Four sided figures are called quadrilaterals. They are usually squares, rectangles, trapizoids, etc..
True
they both have at least one pair of parallel sides and they both are not regular polygons. Parallel lines are two lines that are across from each other and do not cross like a = sign
True. All squares are rectangles, but not all rectangles are squares.
I DO NOT NOW I did not see all. but all i saw true
