A trapezium has normally no lines of symmetry unless it is an isosceles trapezium which has 1 line of symmetry
it has only one line of symmetry.
If it is an isosceles trapezoid, then there is only one line of symmetry, right down the middle of it from top to bottom. If it is a plain old trapezoid with no congruent sides, then there are no lines of symmetry.
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.
a square has 4 lines of symmetry.
There are 6 lines of symmetry if you count sides and not just vertices. (=
A regular hexagon has six lines of symmetry. Lines of symmetry are imaginary lines where you can fold a figure or image and both halves are identical matches.
a rectangle has 4 lines of symmetry
A regularpentagon has 5 lines of symmetryAny pentagon could have less and so can have up to 5 lines of symmetry.
