Carla drew two triangles; triangle ABC and triangle PQR, on a grid. She planned to cut out the two triangles to make a flag. The vertices of triangle ABC are at A(1, 4), B(-2, -1), and C(3, -2). The vertices of triangle PQR are at P(-3, 0), Q(-2, -4), and R(2, 3).

Using the coordinates of the vertices of each triangle explain whether the two triangles are congruent, similar or neither.

Note: I understand I have to apply the formula, but I don't know what goes into it. Help is appreciated.
