Congruent means that the shape is similar in size and shape. Both triangles are the same so we just need to find the order of letters that draw the same triangle. If we draw the triangle LJK and OMN, they both draw the same triangle in the same way with each other. Another way to solve this is that a rule states:
If 3 sides of the first triangle are the same of that of the second triangle, they are congruent.
