Math Grade 8 Quiz Similarity of TwoDimensional Figures – 8.G.A.4
Twodimensional figures are said to be similar if one can be transformed into the other through a sequence of rotations, reflections, translations, and dilations. These transformations maintain the shape’s proportionality and angle measures. When two figures are similar, their corresponding angles are congruent, and their corresponding side lengths are proportional. Understanding the concept of similarity is crucial for various applications, such as realworld modeling and geometric proofs.
