TRANSFORMATIONS, TESSELLATIONS, AND SIMILAR TRIANGLES
Many designs occur naturally or man-made and display properties of transformation. We will look at these types of transformations: translation, reflection, and rotation.
M. C. Escher, who lived from 1898 to 1972, is a famous Dutch artist who created wonderful tessellations, which were drawings and paintings of fish, birds, and reptiles, in which he intertwined mathematics with transformations. The tessellations were congruent shapes that covered the surface of the artwork and fit together like intricate puzzle pieces.
Similar triangles have the same shape but are different in size. The lengths of the corresponding sides are proportional (connect with the same ratio) and the corresponding angles are congruent (equal in measure).
