trapeziod or trapezium
Yes.
In general, an isosceles trapezium (or isosceles trapezoid) does not have perpendicular diagonals. The diagonals of an isosceles trapezium are equal in length and are symmetrical, but they intersect at an angle that is not necessarily 90 degrees. The only quadrilaterals that have perpendicular diagonals are special cases, such as kites and certain rhombuses.
A trapezium is always a quadrilateral.

The 2D shape which has one line of symmetry is the trapezium.
Pentagons can be symmetrical, but are not always so.

Never.
Yes
yes it has four sides
A trapezium (or trapezoid in some regions) is a four-sided polygon (quadrilateral) that has two sides parallel. The sum of the interior angles in any quadrilateral, including a trapezium, is always 360 degrees. Therefore, the angles in a trapezium add up to 360 degrees.
yes, it's always symmetric
