What did you observe when you placed the halves of the cut outs besides the mirror
One would ask that, when seeing writing in a mirror, the writing is backwards but not upside down. Here, we want to figure out why we see things mirrored in mirrors like we do.
When one stares through a mirror, it feels as if one is staring into it and seeing the thing from the other side. It also appears that the object is flipped from left to right. In fact, the right half of the physical object is on the same side as the right half of the virtual object.
Line Symmetry:
Line symmetry When two halves of a figure are mirrored on a line, they become mirror images of each other (also called reflectional symmetry).
• The line of continuity is the dividing line between both the figure's mirror images.
• To see if a figure has line symmetry, fold it down the ostensible line of symmetry to see if the two halves align.
• A figure has a line of symmetry if a reflection in the line will map the figure onto itself.
Plane Symmetry:
The figure has "plane symmetry" if a plane intersects it in such a way that one half of it is the mirrored copy of the other half. In the plane, the figure's two halves are mirror images. Path symmetry in three dimensions is known as plane symmetry.
Plane symmetry can be seen right over us:
Real structures are never "perfectly" symmetrical because tiny defects (even at the atomic level) break the concept of "perfect" symmetry. However, it is common sense to point to a physical object as possessing symmetry if it does so as a whole, without minor flaws.
Rotational Symmetry:
A geometric figure has rotational symmetry if it is the reflection of itself when rotated around a point around an angle with a measure strictly between 0o and 360o. Since they reflect the original position, angles of 0o and 360o are omitted (nothing new happens). The rotational symmetry angles will be factors of 360.
