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.

What are regular and irregular shapes? The definition of a regular shape is that all the sides are equal and all the inside angles are equal. An irregular shape doesn't have equal sides or equal angles. For example, an equilateral triangle is a regular shape because all the sides are equal AND all the angles are equal.

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. ... Consider first lines in a two-dimensional plane.

Odd functions have symmetry about the origin. thus xsinx is an even function.

radial symmetry is for organisms that can be cut an infinite amount of times and still have symmetry. Bilateral symmetry in organisms are organisms that can only be cut once, to gain the equal halves.

A line of symmetry is a line that can be drawn to divide a figure into equal halves. A figure has line symmetry or reflection symmetry when it can be divided into equal halves that match. A figure has reflection symmetry if it can be reflected across a line and look exactly the same as it did before the reflection.

The symmetric shapes are linear, trigonal planar, and tetrahedral. ... If the shape is symmetric, look to see whether all of the atoms attached to the central atom are the same. If so, the molecule is nonpolar. If there is more than one kind of atom attached to the central atom, the molecule is polar.

A quadrilateral with the opposite side lines parallel is known as a parallelogram. If only one pair of opposite sides is required to be parallel, the shape is a trapezoid. A trapezoid, in which the non-parallel sides are equal in length, is called isosceles.

A line through a shape so that each side is a mirror image. When the shape is folded in half along the axis of symmetry, then the two halves match up.

When working with a circle, any line through the center of the circle is a line of symmetry. There are an infinite number of lines of symmetry. Basically, a figure has point symmetry when it looks the same when up-side-down, (rotated 180º), as it does right-side-up.

All regular simple polygons (a simple polygon is one that does not intersect itself anywhere) are convex. Those having the same number of sides are also similar.

Polygons are congruent if they are equal in all respects: Same number of sides. All corresponding sides are the same length, All corresponding interior angles are the same measure.

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 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.

Through any three noncollinear points, there is exactly one plane. A line contains at least two points.

A shape has reflection symmetry if there exists a line of reflection that carries the shape onto itself. This line of reflection is called a line of symmetry. In other words, if you can reflect a shape across a line and the shape looks like it never moved, it has reflection symmetry.
