Reflection in a Line Worksheets
What is a Reflection in a Line? In real life, we consider reflections of images we see when we look in the mirror. Reflection in math, however, follows the same idea. Geometrical reflection correlates with the mirror image in our daily life. Geometrical transformation is used to change the shape and size of a figure or shape. Rigid transformations are those transformations that maintain the length of the shape. Reflection is one of the rigid transformations, that is used to reflect the shape across a defined line. Knowing how to perform reflection of a line is essential for excelling the advanced geometrical skills. In a coordinate plane, we can reflect on the xaxis and the yaxis. A reflection of shape in the xaxis means reflecting an image across the xaxis to obtain a mirror image. In this case, the xaxis is known as the axis of reflection. Similarly, reflection on the yaxis means to reflect a figure or shape across the yaxis to create a mirror image. Here, the yaxis will be known as the axis of reflection. For reflecting the shape across the xaxis, we have to negate every value corresponding to ycoordinate while taking the xvalues as same. For instance, a point P lies on (5,4). When reflecting this point across the xaxis we will get the new coordinates as (5, 4). Similarly, when reflecting any figure across the yaxis, we will negate al the xcoordinates and keep ycoordinate the same. For instance, if we reflect the same point P (5,4) across yaxis, we will get, (5,4).

The Golden Ratio...
The Golden Ratio has fascinated layman and mathematician alike for hundreds of years. It seems like magic, turning up in such different arenas as pine cones, earthmoon and planet relationships, the Cheops Pyramid in Egypt, the Mona Lisa and even our DNA. This widespread appearance exhibits a unifying mathematical principle that is so subtle even science has failed to define it!
