Yes. Any equilateral shape can have both rotational and line symmetry.
It has a degree of 90* * * * *No, it does not. It has 180 degree rotational symmetry.
It is called its order of rotational symmetry depending on its shape as for example a square has rotational symmetry to the order of 4 because it returns to its same shape every time of a turn of 90 degrees and so 360/90 = 4

no shape does! * * * * * Not true. A parallelogram has rotational symmetry of order 2, but no lines of symmetry.
A trapezoid does not have rotational symmetry. Rotational symmetry occurs when a shape can be rotated by a certain angle and still appear the same. In a trapezoid, the angles and side lengths are not equal, so rotating it will result in a different shape. Therefore, a trapezoid does not have rotational symmetry.

none shapes have 1 rotational symmetry because in rotational symmetry one is none
Rotational symmetry is when you turn or rotate a shape and it still looks the same. A circle is the most common answer. However, it you rotate a square about 90 degrees, it still looks the same, so it is considered rotational symmetry. Technically, any shape can have rotational symmetry because it you rotate it 360 degrees, it still looks the same.Definition of rotational symmetry:Generally speaking, an object with rotational symmetry is an object that looks the same after a certain amount of rotation. An object may have more than one rotational symmetry; for instance, if reflections or turning it over are not counted. The degree of rotational symmetry is how many degrees the shape has to be turned to look the same on a different side or vertex. It can not be the same side or vertex.

A shape with 90-degree rotational symmetry is one that looks the same after being rotated by 90 degrees around its center. Common examples include a square and a cross. In these shapes, each quarter turn results in a configuration that is indistinguishable from the original. This type of symmetry is often found in geometric patterns and designs.
A quarter of a circle has one rotational symmetry. Specifically, it can be rotated by 90 degrees to map onto itself. This means the only symmetry that corresponds to rotation is a 90-degree turn, as other rotations would not preserve the shape of the quarter circle. Thus, it has a single rotational symmetry.
