This topic focuses on practicing the application of the Pythagorean theorem within square geometries, specifically determining the length of the sides of a square given the length of a diagonal to the center of the square in decimal values. Each problem provides a different diagonal length and requires the calculation of the respective side lengths using the properties of the Pythagorean theorem. This allows learners to enhance their skills in handling geometric problems involving right triangles and squares, along with practicing decimal arithmetic.
