What type of images is made up of line segments and anchor points?

Vector images are created using line segments and anchor points, making them distinct from other types of images. These images are based on mathematical equations rather than pixels, which allows them to be infinitely scalable without loss of quality. Because vector graphics use paths defined by a start and endpoint, along with other points, curves, and angles, they are ideal for designs that need to maintain sharpness and clarity at various sizes, such as logos and illustrations.

In contrast, raster images are composed of a grid of pixels, which can lead to blurriness or pixelation when resized. Sculptural images refer to three-dimensional representations and do not relate to the definition of images made up of lines and points. 3D images represent depth and volume but do not describe the mechanism of how images are constructed, which is the focus of vector graphics. Thus, the defining characteristic of vector images as being based on lines and anchor points makes them the correct answer.
