A kite, An arrowhead, an isosceles trapezium are three possibilities.
i am not sure but i think a trapezium has 1 order of rotational symmetry

An isosceles triangle
An isosceles triangle has rotational symmetry of order 1.
None.
For example the triskelion (the three legs) on the Isle of Man flag.
The order of rotational symmetry of a equilateral triangle is three. However, the order of an isosceles triangle is one. So, the rotational symmetry depends on the specific type of triangle figure. However, all figures have at least one order. Rotational symmetry is associated with how a shape can be rotated and retains the same or similar appearance.
It depends on the type of triangle. A scalene triangle (no equal sides) has no rotational symmetry. An isosceles triangle (2 equal sides) has rotational symmetry order 2. An equilateral triangle (3 equal sides) has rotational symmetry order 3. The order of rotational symmetry is how many time a shape will fit over itself during one complete rotation.
