![]() ![]() We did this with a point, but the same logic is applicable when you have a line or any kind of figure. If you get four dollars less an hour than (an unknown worker), you wouldnt subtract that workers pay from 4 instead, youd subtract 4 from that workers pay: p 4. ![]() If youre not sure of this, plug numbers in. These three transformations are the most basic rigid transformations there are: Reflection: This transformation highlights the changes in the object’s position but its shape and size remain intact. As the name suggests, the effect a translation has on an object is a slide across. x 4 To be clear, 'four less than (the unknown)' in English means ' (the unknown), less four' in algebra. We will then move the point 3 units UP on the y-axis, as the translation number is (+3). Besides rotations, another common type of transformation is translations. So, we will move the point LEFT by 1 unit on the x-axis, as translation number is (-1). We are given a point A, and its position on the coordinate is (2, 5). ![]() Use the same logic for y-axis if the translation number is positive, move it up, and if the translation number is negative, move the point down. A rotation is a transformation that is performed by spinning the object around a fixed point known as the center of rotation. On our x-axis, if the translation number is positive, move that point right by the given number of units, and if the translation number is negative, move that point to its left. The key to understanding translations is that we are SLIDING a point or vertices of a figure LEFT or RIGHT along the x-axis and UP or DOWN along the y-axis. ![]()
