Essentially. One's a noun, one's an adjective. Things that have symmetry are said to be symmetric.
Yes it does. when tilted it has the same symmetric line.
No such thing as a regular triangle. You need to be more accurate in your triangular description. Equilateral triangle is symmetric about three lines of symmetry. Isosceles triangle is symmetric one line of symmetry. Right-angled, and Scalene triangles have no lines of symmetry.
A sponge is neither bilateral or radial symmetric. It doesn't have any symmetry.
Yes.
The letter A it is vertically symmetric since you can cut it straight down the middle and it will be the same on both sides.
A jellyfish has radial symmetry. A jellyfish is part of the cnidaria species of animals and they generally have radial symmetry. Radial symmetric organisms are like a pie in terms of their shape. THey have no left or right sides. If you were to turn a radial symmetric animal on its side, it would like the same as it did prior.
As the name suggests, they are polygons that have one or more lines of symmetry or rotational symmetry of order two or more. A symmetric polygon is not the same as a regular polygon.
A pentagon can be symmetric, yes. It is symmetric around any of its lines of symmetry. Yes, divide it starting from the top down 2 the bottom. Pretty simple.
A circle is symmetric about ANY diameter. The number of possible diameters of the same circle is infinite. And on the same principle, a sphere will have lines of symmetry in every direction in 3 dimensions.
A figure is symmetric about a line of symmetry if it can be folded along that line, and both halves match perfectly. This means that for every point on one side of the line, there is a corresponding point at the same distance on the opposite side. Additionally, you can check symmetry by reflecting points across the line; the reflected points should lie on the figure itself. If both conditions are satisfied, the figure is symmetric about the line.
Octupii (plural of octupus) are bilaterally symmetric.
Depending on kind of symmetry. It is usually referred to as a shape that is mirrored. So what is on the left half is same as right half, or top is same as bottom. Eg. trapezoid
