I believe it has both.
If you draw planes through the middle of opposite sides e.g. top/bottom, left side/right side, front/back, you will get three planes of (refection) symmetry.
Also if you draw three lines through those same points, you will get three axes of (rotational) symmetry.
The answer is 13- for more detail:
A pentagonal prism has 5 faces, each of which can be rotated to align with the original position. Since there are 5 possible positions where the prism looks the same after a rotation, it has 5 axes of rotational symmetry. Each axis passes through the center of a face and is perpendicular to that face.
Reflectional symmetry
Its extremum is on its axis of symmetry.
It belongs to a family of solid objects with two polygonal faces (sometimes called bases) each with n sides, one of which is translated relative to the other along an axis at right angles to the plane of the polygon; and n rectangles joining them together.
If you ignore the print, then it has a plane of symmetry (possibly) but not an axis of symmetry. If you ignore the print and the "pop-top" part, then it has both.
It depends upon the pyramid: if it is a right rectangular pyramid it will have one axis of rotational symmetry which runs from the apex to the centre of the base and a rotational symmetry of 2. If it is not a right rectangular pyramid then there is no axis of rotation which will permit the pyramid to fit on itself before a complete rotation of 360°
There are three elements of symmetry: 1-axis of symmetry It's a line which cuts the molecule into two equal halves. 2-plane of symmetry It's a plane which cuts the molecule into two equal halves (such as 'axis of symmetry' but axis is a line and here it's a plane). 3-center of symmetry It's a point in space that, if you draw a line from any part to it, and then extend the line beyond it, another atom will be encountered.
No. A square is a plane figure and conventionally for plane figures symmetry is considered in terms of rotation about a point or an axis (in the plane of the figure) but not a plane outside the plane of the square.
Reflectional symmetry
The answer is 13- for more detail:
A prism whose sides are rectangles is called a rectangular prism or a cuboid. In this type of prism, the bases are rectangles, and all the faces are rectangular in shape. Rectangular prisms can have varying dimensions along each axis, making them versatile in form. They are commonly found in everyday objects, such as boxes and buildings.
WF5Cl: C5 axis (rotation by 72 degrees), σh plane of symmetry (horizontal plane that cuts the molecule in half) SiH3CN: C3 axis (rotation by 120 degrees), σv plane of symmetry (vertical plane that cuts the molecule in half)
A pentagonal prism has 5 vertical axes of symmetry that pass through the center of each of the pentagonal bases and the midpoint of the opposite base edges. Additionally, it has 1 horizontal axis of symmetry that runs through the midpoints of the two pentagonal bases. Therefore, a pentagonal prism has a total of 6 axes of symmetry.
A pentagonal prism has 5 faces, each of which can be rotated to align with the original position. Since there are 5 possible positions where the prism looks the same after a rotation, it has 5 axes of rotational symmetry. Each axis passes through the center of a face and is perpendicular to that face.
A molecule possess an n-fold alternating axis of symmetry if,when rotated through an angle of 3600/n about this axis and then followed by reflection of in plane perpendicular to the axis;the molecule is indistinguishable from the original molecule.
Any plane that bisects a cone passing through the pointy tip and the diameter of the base i.e. through the axis of the cone, will be a plane of symmetry. Since any plane passing through the cone this way can be rotated by any angular increment and still remain a plane of symmetry, there are an infinite number of planes of symmetry.
