R, S, and T are the vertices of one triangle. E, F, and D are the vertices of another triangle. m<R = 60°, m<S = 80°, m<F = 60°, m<D = 40°,?
RS = 4, and EF = 4. Are the two angles congruent? If yes, explain how and identify which segment is congruent to RT.

My answer is yes by ASA

  1. clearly the angles are equal
    and immediately we can say that they are similar.

    I used to insist that my students write the triangles in such a way that the vertices correspond in order.
    so
    triangle RST is similar to
    triangle FED

    notice that way angle S = angle E , etc

    since RS = 4 = EF
    they are congruent because of ASA , (angle-side-angle)
