The letter T for example
An equilateral triangle has six symmetries, and an isosceles triangle has two. An isosceles triangle has a single axis of symmetry, the perpendicular bisector of the non-congruent side. This is a reflection symmetry. An equilateral triangle has rotational symmetry as well as reflection symmetry. It is invariant under rotations by 120 degrees.
A parallelogram normally has no lines of symmetry unless it is in the shape of a rectangle which will then give it 2 lines of symmetry
A square, a paralellogram, a trapezoid, a circle, a rectangle, a rhombus.
Not always. It depends where the line of symmetry is located.
It will, unless the shape is symmetrical and the axis of reflection is parallel to the axis of symmetry.
It depends on the shape!

Because linear symmetry defines a line such that the shape is unchanged when REFLECTED in that line.
A square, a paralellogram, a trapezoid, a circle, a rectangle, a rhombus.
No. You can reflect any shape about a line but if the resulting image is not the same as the original, that line is not a line of symmetry.
Not always. It depends where the line of symmetry is located.
Reflection symmetry, reflectional symmetry, line symmetry, mirror symmetry, mirror-image symmetry, or bilateral symmetry is symmetry with respect to reflection
None - it has rotational symmetry - not reflection symmetry.
A rectangle is one of them
