Find the perimeter of the figure to the right

Which statement explains the relationship between corresponding terms in the table?

For the right triangle shown, the lengths of two sides are given. find the third side. leave your answer in simplified, radical form.

Graph a triangle (xyz) and reflect it over the line y=x to create triangle x’y’z’. describe the transformation using words. draw a line segment from point x to the reflecting line, and then draw a line segment from point x’ to the reflecting line. what do you notice about the two line segments you drew? do you think you would see the same characteristics if you drew the line segment connecting y with the reflecting line and then y’ with the reflecting line? how do you know?
