Answer AThe triangle that isn't shaded has the following vertices: left-parenthesis 1 comma 2 right-parenthesis, left-parenthesis negative 3 comma negative 1 right-parenthesis, and left-parenthesis 1 comma negative 1 right-parenthesis. This vertex is a right angle. The shaded triangle has the following vertices: left-parenthesis 2 comma 5 right-parenthesis, left-parenthesis 2 comma 8 right-parenthesis, and left-parenthesis 6 comma 5 right-parenthesis. The first vertex is a right angle.
