There are many. An isosceles triangle, for example.
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
Yes, a regular pentagon has reflection symmetry. It has five lines of symmetry, each passing through a vertex and the midpoint of the opposite side. However, an irregular pentagon may or may not possess reflection symmetry, depending on its specific shape.
Shapes can exhibit several types of symmetry, including reflective symmetry, where one half is a mirror image of the other; rotational symmetry, where a shape looks the same after being rotated by a certain angle; and translational symmetry, where a shape can be moved (translated) along a certain direction and still appear unchanged. Additionally, some shapes may possess glide reflection symmetry, which combines reflection and translation. Each type of symmetry contributes to the overall aesthetic and mathematical properties of the shape.
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
A rectangle is one of them
None - it has rotational symmetry - not reflection symmetry.
