![]() We did this with a point, but the same logic is applicable when you have a line or any kind of figure. We will then move the point 3 units UP on the y-axis, as the translation number is (+3). 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. ![]() provides you with clear explanations and diagrams to help you master reflections. Dilation is not limited to two-dimensional figures. Dilation is a type of similarity transformation, which means that the shape of the figure remains the same, but its size changes. It determines the magnitude of the size change. So, we will move the point LEFT by 1 unit on the x-axis, as translation number is (-1). Learn how to reflect a point across different lines, such as the x-axis, the y-axis, the line yx, and the line y-x, with interactive examples and activities. The dilation scale factor can be any real number, including fractions and decimals. We are given a point A, and its position on the coordinate is (2, 5). Step 2: Extend the line segment in the same direction and by the same measure. Since the reflection line is perfectly horizontal, a line perpendicular to it would be perfectly vertical. A congruent quadrilateral with has vertices E prime at negative seven, negative four, F prime at negative three, negative two, G prime at negative four, negative eight, and H prime at negative eight, negative seven. 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. We can find the translation by figuring out how much the x- and y-coordinates need to change to map one triangle onto the other. Step 1: Extend a perpendicular line segment from A to the reflection line and measure it. 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. ![]() Which image is the translation of ABC given by the translation rule (x, y) -> (x - 2, y + 2) X to the left 2 units, Y up 2 units. 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.
