Transformations Of 2 Dimensional Shapes Skillsyouneed A reflection is a kind of transformation.conceptually, a reflection is basically a 'flip' of a shape over the line of reflection. reflections are opposite isometries, something we will look below. Step 4: reflect the points. to reflect each point over the line of reflection, you need to find its corresponding point on the other side of the line. to do this, draw a line perpendicular to the line of reflection from the original point to the line of reflection. then, extend this line to the other side of the line of reflection. In a reflection transformation, all the points of an object are reflected or flipped on a line called the axis of reflection or line of reflection. example: a reflection is defined by the axis of symmetry or mirror line. in the above diagram, the mirror line is x = 3. under reflection, the shape and size of an image is exactly the same as the. Example 3: reflect a shape on a coordinate grid. reflect triangle p p in the line x=4 x = 4: draw the mirror line. the mirror line is x=4 x = 4 (the line of reflection). this is a vertical line. draw this on the diagram. 2 reflect the other points. choose the first point to reflect.
