HELP In the diagram, line x is parallel to line y, mZ1 = 65°, and m27 = 55°. Stuart says that
m212 = 60°. His reasoning is shown.
Step 1: m 28 = 60°, because mZ1 + m27 + m28 = 180°.
Step 2: Z8 212, because 28 and Z12 are corresponding angles.
Step 3: So, mZ12 = 60°

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?
