From the information given, determine which triangles, if any, are congruent and state by which rule. If the triangles cannot be shown to be congruent, write, "Cannot be determined," and explain.

Cannot be determined

Step-by-step explanation:

The triangles are not congruent because it follows the pattern Side-Side-Angle, and the triangles are not right triangles, so they cannot be congruent by hypotenuse-leg. Side-Side-Angle is not a congruent rule. It is only Side-Angle-Side, Angle-Side-Angle, or Side-Side-Side.

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.

the answer is c 150
