The original shape is the object and the translated shape is the image. Make sure you know which shape is the original shape and start there when describing transformations such as translations. A positive moves the shape upwards and a negative number moves the shape downwards. Its easy to find a couple examples of reflections, rotations, and translations. The bottom number is for vertical movement. If youre teaching transformations in geometry, this project idea is. A positive number moves the shape to the right and a negative number moves the shape to the left. Remember, the top number is for horizontal movement. \beginīut if by considering the scale on the axes, the correct column vector is ![]() If we count the squares it may appear that shape P has been translated by the column vector What is the column vector for the translation of shape P to shape Q? Using tracing paper can be useful when translating shapes.īe careful to consider the scaling on the axes. The object and the image are congruent because they are the same shape and the same size. When an object is translated the object and the image have the same orientation. The image is the name of the shape after it had been translated. The object is the name of the original shape. The inverse transformation would translate shape B back to shape A using the column vector: The column vector gives instructions how to move each point of the original shape. Shape A has been translated to shape B by the column vector ![]() We use a column vector to help record the movement. In this paper, some real-world motivated examples are provided illustrating the power of linear algebra tools as the product of matrices, determinants. Translation is a type of transformation that moves a shape in a horizontal direction (left and right) and in a vertical direction (up and down).
