ANSWER QUICK: Which best describes the relationship between the two triangles below? Triangle M N L. Angle M is 51 degrees and angle L is 36 degrees. Triangle F H G. Angle F is 51 degrees and angle G is 36 degrees. Triangle M L N is similar to Triangle F G H because of the third angle theorem, Angle M is congruent to angle F, Angle L is congruent to angle G, and Angle N is congruent to angle H. Triangle M L N may or may not be similar to Triangle F G H because the third angle is unknown. Triangle M L N is similar to Triangle F G H because of the angle-angle criterion, Angle M is similar to angle F, Angle L is similar to angle G, and Angle N is similar to angle H. Triangle M L N may or may not be similar to Triangle F G H because the side lengths are unknown.
