A definition of a trapezoid is a pair of parallel line, and 2 other sides which close the loop. If a quadrilateral is known to be a trapezoid, it is not sufficient just to check that the legs have the same length in order to know that it is an isosceles trapezoid, since a rhombus is a special case of a trapezoid with legs of equal length, but is not an isosceles trapezoid as it lacks a line of symmetry through the midpoints of opposite sides. 1) trapezoid 2) regular pentagon 3) circle 4) square 14 On the accompanying square, draw all the lines of symmetry.
