Part 1:
In this unit, you learned about three acceptable criteria for identifying congruent triangles: angle-side-angle (ASA), side-angle-side (SAS), and side-side-side (SSS). In each of the following, Tell if the triangles are congruent. If the triangles are congruent, state the Postulate or Theorem that verifies it. If not, write NONE. Each question is worth 0.5 Points.

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
