Transformations - Translations
When looking at two figures, you know which one is the transformation because the one who is that transformation has an apostrophe sign. For example, M is the original and M' is the transformation. The new points are called prime (which is what the apostrophe stands for). Another word that you can use to describe a translation is sliding. A translated figure will never change shape because translating means to slide a figure up, down and across any number of units. You can translate a figure without using a coordinate plane by seeing on how many units you have to slide the figure. For example, if you have to translate a figure 5 units to the right and the original figure is on the points, (5,3) you will have to add 5+5 because when your sliding it to the right, you are moving it on the x-axis and the x-axis is the first number, which in this case is 5 because u started with (5,3). In other words, you can translate a figure by finding out if your going to slide it on the x-axis or the y-axis, if you going to the left u will be subtracting from the x-axis and if u go to the right, you will be adding it. And if you go up on the y-axis, you will add and if u go down, you will subtract.
