Bilateral Symmetry
Bilateral symmetry is the type of symmetry in which an organism can be divided into two equal halves that are mirror images of each other along a central axis. This symmetry is commonly found in animals that are adapted for forward movement and have distinct front and back ends.
A quarter circle has one axis of symmetry. An axis of symmetry is a line that divides a shape into two equal halves that are mirror images of each other. In the case of a quarter circle, if you draw a line through the center of the circle perpendicular to the diameter, it will divide the quarter circle into two equal parts that are mirror images of each other.
When folded over, the right and left halves of the face, palms, and feet match up as mirror images. This is due to bilateral symmetry in the human body where the right and left sides are essentially mirror images of each other.
The different types of symmetry are rotational symmetry whereby the various object parts are related by rotation angles, and reflectional symmetry where halves of the object form the mirror images.
A dotted line can be a line of symmetry if it divides a shape into two equal parts that are mirror images of each other. In geometry, a line of symmetry is a line that divides a shape into two congruent parts. Whether a dotted line is a line of symmetry depends on the specific shape and the placement of the line.
A line that divides the letter so that the 2 halves are mirror images. Ex. The letter V ... A vertical line thru the bottom makes 2 parts that are mirror images, so that vertical line is the axis of symmetry. But.. A Capital E would not have a vertical axis of symmetry. Capital E would have a horizontal line splitting thru the middle line as its axis of symmetry.
It is a line of symmetry.
A shape has symmetry if it can be divided into parts that are arranged in a balanced and proportional manner. This means that one half of the shape is a mirror image of the other half, or it can be rotated or reflected and still appear the same. Common types of symmetry include bilateral (mirror) symmetry and rotational symmetry. Symmetry is often associated with beauty and harmony in design and nature.
A line of symmetry is an imaginary line that divides a shape into two identical halves that are mirror images of each other. For example, in a rectangle, the vertical line drawn through the center creates two equal parts, while in a circle, any line through the center is a line of symmetry. Shapes can have multiple lines of symmetry; for instance, a square has four lines of symmetry.
The three types of symmetry are bilateral symmetry (division into two mirror images), radial symmetry (division into multiple symmetric parts around a central axis), and translational symmetry (repeating patterns along a straight line).
In bilateral symmetry (also called plane symmetry), only one plane, called the sagittal plane, will divide an organism into roughly mirror image halves (with respect to external appearance only, see situs solitus). Thus there is approximate reflection symmetry. Often the two halves can meaningfully be referred to as the right and left halves, e.g. in the case of an animal with a main direction of motion in the plane of symmetry.
A smiley face typically has two lines of symmetry: one horizontal line passing through the middle of the face, and one vertical line passing through the center of the face. These lines divide the smiley face into four equal parts that are mirror images of each other.
