Easy question 21 points The vertices of a triangle are P(5,7), (3, 4), and R(-2,6). What are the vertices of the image reflected across the x-axis?
P'(-5, 7), Q'(-3, 4), and R' (2,6)
P(5,7), Q'(3,4), and R' (2,6)
P'(-5.-7), O'(-3,-4), and R'(2-6)
P(5.-7), (3, 4), and R'(-2,-6)

When constructing a perpendicular line through a point off a line, how can you verify that the lines constructed are perpendicular? check the angles used in the construction with a straightedge to ensure consistency. check the distance along the lines at several places with a compass to ensure they are the same length. check the intersecting lines with the corner of a piece of paper to ensure the lines create 90° angles. check the distance between the lines at several places with a compass to ensure they are equidistant. question 2(multiple choice worth 1 points) (01.03 lc) which of the following steps is included in the construction of a perpendicular line through a point on a line? connect arcs that are above and below the given line with a straightedge. connect arcs that are above the original line with a straightedge. create arcs on either side of a point that is off the given line. create a copied angle by using the first two lines as the original angle.
