Reflection Line Math Definition

For k 12 kids teachers and parents.

Reflection line math definition. Every point is the same distance from a central line. A line of reflection is also a line of symmetry if a geometric shape or figure can be reflected across the line back onto itself. A reflecting line is a perpendicular bisector. Learn about reflection in mathematics.

Line of reflection. Try this drag any orange dot to move the line of reflection or reshape the triangle. It is a line that is reflected over in a reflection. Reflecting the right side of the butterfly across line l maps it to the butterfly s left side.

The reflection formed on a line is a transformation. Reflection of a polygon a transformation where each point in a shape appears at an equal distance on the opposite side of a given line the line of reflection. The length of each segment of the preimage is equal to its corresponding side in the image. Try this drag the endpoints of ab or drag the point l to move the line of reflection.

Their image is flipped over the. The same result occurs if the left side of the butterfly is reflected across line l so line l is also a line of symmetry. In the following picture the birds are reflected in the water. Here s a problem that uses this idea.

Reflection of a line segment a transformation where every point on a line segment appears an equal distance on the other side of a given line the line of reflection. When a figure is reflected the reflecting line is the perpendicular bisector of all segments that connect pre image points to their corresponding image points. Though a reflection does preserve distance and therefore can be classified as an isometry a reflection changes the orientation of the shape and is therefore classified as an opposite isometry. In the following figure triangle j k l is the reflection of triangle jkl over a reflecting line.

A reflection of an object is the flip of that object over a line called the line of reflection.
