Understand that a two-dimensional figure is similar to another if the second can be obtained from the first by a sequence of rotations, reflections, translations, and dilations; given two similar two-dimensional figures, describe a sequence that exhibits the similarity between them. Then tell students that the Pythagorean Theorem says: If \(a\), \(b\), and \(c\) are the sides of a right triangle, where \(c\) is the hypotenuse, then. This will rely heavily on the use of special right triangles. This is written as . The two legs meet at a 90 angle and the hypotenuse is the longest side of the right triangle and is the side .
