Not sure about angels and parrellel,
but a trapezium has four angles and only one pair of parallel lines.
Trapezoid
In 2 dimensions, a polygon. In 3 dimensions, a polyhedron.
A hexagon is the simplest shape, and the only regular polygon, with 6 lines of symmetry.
a trapezoid has only 1 parrellel side and a rhombus has 2
It can only be none other than a trapezoid.
Shapes that only have two lines of symmetry:SquareRectangleParallelogram
A square
Then it wouldn't be a shape then it would only be 2 parellel lines
yes in half only
Trapezium.
Because it only has four sides. So it can only have two lines of symmetry because if you fold it the sides will be the same shape.
The only shape that has 4 lines of symmetry is a square.
