Pq and rs are two lines that intersect at point t. which fact is used to prove that angle pts is always equal to angle rtq?

a.) the sum of the measures of angles rtq and qts is equal to the sum of the measures of angles qts and pts.
b.) angle rtq and angle qts are complementary angles.
c.) the sum of the measures of angles rtq and pts is equal to the sum of the measures of angles rtp and qts.
d.) angle rtq and angle pts are supplementary angles.

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.
