what are 2 lines of symmetry?

Two Lines of Symmetry can be a combination of Vertical, diagonal or Horizontal Lines. Letters such as H and X also have two lines of Symmetry. An hourglass is also an example of Two Lines of Symmetry. A rectangle does not have a diagonal line of symmetry as opposed to square as its sides are not the same.

The term "high symmetry" refers to the fact that at such a local point you have more symmetry elements that copy this point onto itself. You need to distinguish direct and reciprocal space though.

There are two major lines of longitude—the prime meridian and the international dateline. There are five lines of latitude—the equator, the Tropic of Cancer, the Tropic of Capricorn, the Arctic Circle, and the Antarctic Circle.

A 2D shape is symmetrical if a line can be drawn through it so that either side of the line looks exactly the same.

A line is a straight one-dimensional figure having no thickness and extending infinitely in both directions. A line is sometimes called a straight line or, more archaically, a right line (Casey 1893), to emphasize that it has no "wiggles" anywhere along its length.

Folding Test You can find if a shape has a Line of Symmetry by folding it. When the folded part sits perfectly on top (all edges matching), then the fold line is a Line of Symmetry. Here I have folded a rectangle one way, and it didn't work.

On the graph of a quadratic, whatever is happening m units to the left of the vertex, the same thing must be happening m units to the right of the vertex. Hence, symmetry!

The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.

Options: If the signs all stay the same or all change, f(-x) = f(x), then you have even or y-axis symmetry. If either the numerator or the denominator changes signs completely, f(-x)= -f(x) then you have odd, or origin symmetry. If neither of the above, then there is no symmetry.

With Rotational Symmetry, the image is rotated (around a central point) so that it appears 2 or more times. ... Point Symmetry is when every part has a matching part: the same distance from the central pointbut in the opposite direction.

Remember that symmetry is the word given to define when the exact same shape appears across a line or point. Line symmetry is perhaps the easier to understand, as it involves a mirror image. ... Rotational symmetry refers to that kind of symmetry that is rotated around a point.

The letter Z is an example of "2-fold Rotational Symmetry"; it looks the same after being rotated by 180° around its center. But it does not have mirror symmetry. Shapes like this are called "chiral", which means that they can not be superimposed on their mirror images.

Two lines are parallel lines if they are coplanar and do not intersect. Lines that are not coplanar and do not intersect are called skew lines. Two planes that do not intersect are called parallel planes.

PRINCIPLES: Balance – can be Symmetrical or Asymmetrical. Symmetrical = dividing a composition into two equal halves with seemingly identical elements on each side. Repetition/Rhythm – a repeating visual element (line, shape, pattern, texture, movement); a flowing and regular occurrence.

Two angles in the same position are called corresponding angles. They have the same measure if the original two lines are parallel.
