Final answer:
Triangle JLM is congruent to KLM through the perpendicular bisectors, medians, and altitudes.
Step-by-step explanation:
Triangle JLM is congruent to KLM through the perpendicular bisectors, medians, and altitudes.
Perpendicular bisectors: If the perpendicular bisectors of the sides of two triangles intersect at a point, then the triangles are congruent.
Medians: If the medians of the sides of two triangles intersect at a point, then the triangles are congruent.
Altitudes: If the altitudes of the sides of two triangles intersect at a point, then the triangles are congruent.
