Dilation is a transformation in geometry that involves changing the size of a figure while keeping its shape and orientation the same. In 8th-grade math, students are required to master the skill of dilating figures as per common core math teacher.
To dilate a figure, students must first choose a center of dilation and a scale factor. The center of dilation is the point about which the figure is dilated, and the scale factor determines how much the figure is enlarged or reduced.
Students must then apply the scale factor to each vertex of the figure to find the coordinates of the dilated figure. This requires a good understanding of coordinate geometry and the ability to perform basic arithmetic operations.
With practice, students can master the skill of dilating figures and apply it to more complex problems in geometry, such as finding the area and perimeter of dilated figures.
