if the mesure of one angle created by the intersection of 2 lines is 90 degrees then all 4 of the angles created by the intersection of 2 lines will measure 90 degrees true or false

What is the answer to the question 5x+2x

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?
