![]() ![]() The reflected image is the same size and shape as the original object. So their reflection will be 4 squares to the right of the line. The other two corners furthest from the mirror line are both 4 squares left of the line. Their reflection will be 2 squares to the right of the line. The two corners nearest to the mirror line are 2 squares to the left of the line. We count how far away from the mirror line each point is and reflect it the same distance to the other side of the line. ![]() The first step is to mark the corners of the trapezium. Here is another example of reflecting a shape on a grid in a vertical mirror line. The original shape is called the object and the reflected shape is called the image. Once all corners have been reflected, the final step is to connect them with a ruler. The other two corners of the triangle are 3 squares to the left of the mirror line and so, their reflection will be 3 squares to the right of the mirror line. Its reflection is 1 square to the right of the mirror line. The corner nearest to the mirror line is 1 square to the left of the line. When reflecting shapes on a grid, we can simply count the number of squares each corner is away from the mirror line. We then use a ruler to measure how far away each corner is from the mirror line. The first step is to mark each of the corners of the triangle. Here is an example of reflecting a triangle in a line or reflection. Join the reflected corners together to create the reflected image of the shape.Repeat this for each corner of the shape.This is the position of the reflected corner.Without moving the ruler, measure this same distance from the mirror line but on the other side of the line.Measure how far away the corner is from the mirror line.Place a ruler on one of these corners and on the mirror line so that the ruler is at right angles to the mirror line.To reflect a shape in a mirror line use the following steps: The end of the arrow is still one square away from the mirror line and the tip of each arrow is 4 squares away from the mirror line.Īfter reflecting a shape, each point on the shape is the same distance away from the line of reflection but on the other side of the mirror line. After it has been reflected in the mirror line, it now points right. We can see in this example above that the arrow is pointing left to begin with. The mirror line is the line that the shape is reflected in. The reflected image will now be facing in the opposite direction to the original object. Each point in the shape is moved to the other side of the mirror line but remains the same distance away from the line. Reflecting a shape simply means to flip it over a mirror line. ![]()
