What are the properties of a trapezium?
The TRAPEZIUM has one pair of opposite sides that are parallel.In America, a trapezium is a convex quadrilateral with no parallel sides. In the United Kingdom and Australia, a trapezium is defined as a convex quadrilateral with one pair of parallel sides (a trapezoid in America).A trapezium always has two parallel sides. Some trapeziums have 1 line of symmetry, these are called isoceles trapeziums
Draw a quadrilateral with no parallel sides?
draw a square then tilt one line from each pair of parallel sides away from its pair then adjust the lengths of the top and bottom sides to make it match
What makes a parallelogram a parallelogram?
A parallelogram is a quadrilateral in which each of two sets of opposite sides consists of two parallel lines (or for math purists I should say, parallel line segments).
What is the name of a shape with 1 parallel line and 1 symmetry?
You cannot have one parallel line. There must be another line that it is parallel to. Also, 1 symmetry is meaningless - you can have one axis of symmetry or rotational symmetry of order one. The answer will depend on which one it is.
Why does a square have more lines of symmetry than a rectangle?
The diagonals of a rectangle aren't lines of symmetry unless it's square.
